@DavidPostill I'm kinda curious why superuser.com/a/1475229/117590 was deleted, if you don't mind sharing?

It makes exactly the point I was thinking of while reading the other ones...

@Ave I had the nokia one of those ... e65? was a pretty nice phone, combined with opera

Ditto for what Kevin said. As a C/C++/etc compiler engineer in a previous career, our position was that undefined behavior could crash your program, screw up your output data, set your house on fire, whatever. But the compiler should never crash no matter what the input. (It might not give helpful error messages, but it should produce some kind of diagnostic and exit rather than just screaming CTHULHU TAKE THE WHEEL and segfaulting.) — Ti Strga 7 hours ago

@bwDraco is this likely to be any good? aliexpress.com/item/…

Journeyman Geek

@rahuldottech U2 though

rahuldottech

Also, why do SATA m.2 SSDs cost so much more than regular SATA SSDs of the same capacity?

Journeyman Geek

not sata

rahuldottech

@JourneymanGeek One U2, one SATA. Both can operate at the same time. I know nothing about U2. Is it bad?

Journeyman Geek

@rahuldottech U.2 is basically a PCIe interface for server SSDs

So you couldn't install it on an arbitrary PC

rahuldottech

15:05

@JourneymanGeek Hmm.

Journeyman Geek

U.2, formerly known as SFF-8639, is a computer interface standard for connecting SSDs to a computer. It covers the physical connector, electrical characteristics, and communication protocols. It uses up to four PCI Express lanes and two SATA lanes. It was developed for the enterprise market and designed to be used with new PCI Express drives along with SAS and SATA drives. == History == The Enterprise SSD form factor was developed by the SSD Form Factor Working Group (SFFWG). The specification was released on December 20, 2011, as a mechanism for providing PCI Express connections to SSDs for...

Journeyman Geek

oh no good then

rahuldottech

why not? :/

Journeyman Geek

NO WORKY

rahuldottech

15:07

WHY NO WORKY THOOOOOO

Journeyman Geek

Because its basically a physically and electrically different connection from sata

rahuldottech

@JourneymanGeek Hence the circuitry on the thingy tho??

Journeyman Geek

looks passive

looks also like it breaks out one slot as sata and one slot as PCIe

rahuldottech

@JourneymanGeek so confirmed no worky on my laptop?

Journeyman Geek

fairly certain

rog.asus.com/articles/hands-on/…

rahuldottech

15:12

So this won't tell me if it the m.2 is an AHCI or an NVME

But seeing as it's a 2018 model, it's same to assume the latter?

Journeyman Geek

@rahuldottech find and check the service manual

rahuldottech

I'd open it up and see for myself, but the machine won't arrive till the 4th and I want to have an SSD ready to install by then

Journeyman Geek

h10032.www1.hp.com/ctg/Manual/c06248869

suggests either

but the optane model uses one slot

but has NVMe support

but depends on how big the drive is

page 68

rahuldottech

@JourneymanGeek The one I'm getting doesn't ship with optane

NVMe SSD it is, then. Thanks!

Bob

Look at the keying.

There's different slot keying for SATA, NVMe and "both"

Journeyman Geek

15:20

yup

but I doubt that HP would have different models

only both

Bob

Hm. Actually, I take that back.

I thought SATA-only used a different key ... but apparently not o_O

rahuldottech

Actually, idk. My laptop will come with a 128 gig NVMe SSD (hopefully not dramless!), and a 1TB HDD. Looks like it'll be cheaper for me to upgrade the HDD, since regular SATA SSDs cost way less than m.2 SSDs

I'll let the m.2 remain as is, and get a 250gb SATA one to replace the HDD?

I honestly want to upgrade both, but budget won't allow for that atm.

Bob

yea, toss the hdd

Journeyman Geek

eh nothing wrong with dramless

Bob

will help power usage and weight too

dramless is fine for most purposes

rahuldottech

15:24

@Bob yeah, that's what I was thinking

@JourneymanGeek lol, I just recall draco ~~hating on them~~ saying that they have worse performance

Cool, that's decided then!

Journeyman Geek

@rahuldottech I have a pair of them that have served well

across a few machines actually

rahuldottech

I'm so excited about this new laptop :)

Journeyman Geek

not really worth it any more (mainstream drives have dropped pretty comparably to the chinesium ones) but they've worked well

rahuldottech

That's good to know :)

Only one more week to go...

Bob

@JourneymanGeek eh, there's tiers

I won't go for kingdian etc

but you can get perfectly good (dramless) crucial, kingston, etc drives for a fair bit less than the 'mainstream' ones

Journeyman Geek

15:38

@Bob kingdian etc are not much cheaper than said seamless models

rlemon

hallo

so I'm trying to setup some kiosk type application

the x session?window keep starting off screen about 30%

nothing seems to want to correct it

#!/bin/bash

xset s noblank
xset s off
xset -dpms

matchbox-window-manager -use_titlebar yes &

# chromium-browser --start-maximized --kiosk --disable-gpu
xterm -geometry 1000x200+500+500

so like.. in this. xterm starts with about 30% of the left side cut off

(chromium as well)

geometry settings seem to be ignored

same with --size and fullscreen options for chrome

any insight would be helpful

djsmiley2k

hey @rlemon

rlemon

howdy

djsmiley2k

i'll try and help, as you made me laugh about javascript some time

rlemon

very simple setup I have

djsmiley2k

can you fire up the xterm, then fire up xinfo and click the xterm?

it sounds like X is very confused about the size of your actual display

rlemon

19:23

ubuntu server
matchbox window manager installed
chromium installed
chromium and xterm open way off screen (incoming pic)

chromium allows keyboard input

xterm for whatever reason does not

djsmiley2k

o_O

rlemon

but I can't see the left side. so maybe it's prompting me or column limited

but blind commands do nothing

djsmiley2k

hold down a until something appears?

rlemon

tried it

djsmiley2k

hmmmm ok.

rlemon

19:24

but will try again

djsmiley2k

can you switch into a tty and view xorg logs?

rlemon

don't want to leave anything to chance. this is not my forte

djsmiley2k

Also, have you tried seeing if you can fire up chromium maximised?

Does it then 'fit' the screen, or is it still off the edge?

rlemon

tried maximized, kiosk, and manually setting size to 800*600

besides the titlebar changing

no size differences

djsmiley2k

..... dafaq?

rlemon

19:26

ohh fuck

djsmiley2k

You sure you're not at 640x480 or somethinge even worse?

rlemon

I just tried to see exactly how big the screen was in chrome

djsmiley2k

svga? XD

rlemon

opened dev tools

docked it to the left side instead of the righ t

fml

djsmiley2k

How small is it? or can't you even see?

We can likely fix it, if that's the issue at least...

rlemon

19:27

the left.. 30/40% is cut off

user image

djsmiley2k

Do you have another monitor btw?

rlemon

tried on another

same deal.

both are the same size tho, different vendors

djsmiley2k

Oh infact, just try ctrl alt f1 - can you see the login prompt?

or is that also off the edge of the screen...

rlemon

not on that tty, but I can get to tty2 just fine

djsmiley2k

/me trying to figure out if it's just Xortg that's bust

rlemon

19:28

this is only after loading x

yes, it's just xorg

djsmiley2k

Can you install xrandr?

/me doesn't know if ubuntu has it, but it might help in this case

or arandr

rlemon

yea. lemmy google them first

djsmiley2k

Sure

rlemon

looks suspiciously :P

djsmiley2k

they're for configuring screens

:D

randr is the searches for term, comes up with driver that allow weird screen sizes/stretching/etc

Tis not a driver as it's not in the kernel, but it might help

or if ubuntu has something for configuring X org and telling it to stop being so retarded

rlemon

19:30

you know what the package name is?

x11-server-utils

djsmiley2k

I wonder if this is some weird ass framebuffer stuff

rlemon

seems to be what it's recommending

> Package xrandr is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
x11-xserver-utils

djsmiley2k

helpfully this page doesn't help

wiki.ubuntu.com/X/Config/…

ah, that'll be the one :D

your machine isn;t some weird jhardware thats meant to have a customer facing screen attached is it?

rlemon

nope

embedded, but doesn't seem too limited from what I've used in the past

> Desktop screen - left side not visible, menus beyond reach

I did have a look at dconf settings before I did your reset. There was a line: "x-offset=48" and I'm sure this was the cause of the problem, shifting the screen. The dconf settings when I logged in as the other user did not have this line.
How on earth it got there I do not know. Maybe it was me in a past life

rlemon

19:38

is it possible that changed in the last 3 hours?

because this is a fresh install

Ubuntu server 18.04.3

but I will reset them

nothin

rahuldottech

@JourneymanGeek I have a Yamaha synth service manual from 2001 which has better images than that joke of an HP service manual

djsmiley2k

19:53

@rlemon as in it did it before the install?

Gnome desktop screen is offset to the right by 1/2 Icon

After logging in the ntire desktop screen is at the right resolution but offset to the right by about half an Icon.There is a dark stripe along the left and the trash can is half way off to the right. When you change the resolution to another supported value, say, 800X600 and then choose the "use previous resolution" button. the screen comes back properly centered with everything visible. Sometimes the screen corrects itself when comimg back on after the screen saver. This behaviour happens in Suse 10.0 and 10.1 also. The resolution I'm using is 1280 X1024 I have an HP Pavilion760n with an ATI radeon all-in-wonder 7500 and Princeton VL1916 LCD monitor running on the DVI connector I haven't tried the 3d acceleration or the tv functionality yet. My Laptop, an Averatec 6110 with a resolution of 1280 X 800 doesn't do this. I did an online upgrade from Breezy to Dapper on that machine that went flawlessly.

xserver-xorg-video-ati (Ubuntu)

Low / Invalid

Did you manage to get xrandr?

or see if you have xvidtune

might need running with sudo, as it directly effects xorg appently o_O

rlemon

I got xrandr

djsmiley2k

k, xrandr --query ?

rlemon

when and where?

on a new tty while x is open?

or before I run x on the same tty?

djsmiley2k

oh, hmmm need to run it in x

but you can't see any output in a xterm?

rlemon

nope

djsmiley2k

20:07

oh we could try writing to a file and read it out after

rlemon

we could

or echo it from xinitrc

would that work?

djsmiley2k

xrandr --query > ~/xrandr-output

errr it should I guess? :D

rlemon

blank

but only actually created the log when I added stderr output

but created it blank

odd

djsmiley2k

hmmm

i just tested my command and it worked here

I'm guessing it's complaining there's no monitor yet

rlemon

maybe

I'm also distracted because my friend just made an app that adds a juicebox to pictures

and it's very fun

not just any juicebox

my juicebox

djsmiley2k

20:15

ah

if you set the DISPLAY variable

then you can run xrandr from another tty

DISPLAY=0:0
xrandr --query | wgetpaste

rlemon

ahhhh

I can see it now

current: 2944 X 1080

that's an issue

djsmiley2k

:)

xrandr --query should list all the modes the monitor can do

>DVI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm
1920x1080 60.00*+
1600x1200 60.00
1680x1050 59.88
1280x1024 75.02 60.02
1440x900 59.90
1280x960 60.00
1152x864 75.00
1024x768 75.03 70.07 60.00
832x624 74.55
800x600 72.19 75.00 60.32 56.25
640x480 75.00 72.81 66.67 59.94
720x400 70.08

Like so....

If you don't have the 'right' one showing, you can force it (warning, you used to be able to blow up monitors via this).

> xrandr --newmode <name> <clock MHz>
<hdisp> <hsync-start> <hsync-end> <htotal>
<vdisp> <vsync-start> <vsync-end> <vtotal>
[flags...]
Valid flags: +HSync -HSync +VSync -VSync
+CSync -CSync CSync Interlace DoubleScan

Hopefully you can see the right one listed? if so xrandr --output <name of output> --mode 1024x768

And hopefully finally, after ~3 years, I've paid my javascript debts !

I infact have a 'fix screens' bash script i run to add the correct mode and switch to it at a reboot

because my system too is dumb

rlemon

20:31

hold on it has some other outputs that might be of use

gist.github.com/rlemon/db32f10bd4dff130912372435be592e8

so it says current at the top

but also it knows the monitor I'm connected too is 1920x1080

the +1024 tho

why would it randomly put that offset :/

stupid

djsmiley2k

it thinks there's 2 monitors

one which is 1024xwhatever

so it offsets the '2nd' one

rlemon

it has two ports, a hdmi and a vga

only the vga is connected

but I'm also ssh'ing into it

if that matters

djsmiley2k

xrandr --output eDP-1 --mode off

rlemon

if it's thinking there is a DP on there.. I did first try to hook it up a monitor with a hdmi -> dp cord

djsmiley2k

nah, but the gfx isn't reporting that the DP is disconnected

or.... something isn't

I'm not a deep kernel wiz

but that command should turn that monitor off for you might fix things

rlemon

20:36

cannot find mode off

djsmiley2k

oh whoops

--off

xrandr --output eDP-1 --off

rlemon

> xrandr: Configure crtc 0 failed

djsmiley2k

o_O

herh

lets stick it on the right of the 'real' monitor?

xrandr --output eDP-1 --right-of VGA-1

or maybe xrandr --output VGA-1 --primary

rlemon

would I see these changes live?

djsmiley2k

the moving the screens I think so yes.

rlemon

20:40

xrandr --output VGA-1 --same-as eDP-1

worked

\o/

djsmiley2k

primary tells windows to open in the 'right' place

i.e. they'll open with the +1024 offset

Awesome :)

rlemon

danke

much appreciate all the help

been at this since last night

not the positioning. just hte kiosk business

djsmiley2k

no worries, like i said, you helped me out long ago when i wasn't in the greatest of places :D

as a perm fix you could run that command every time, you can likely 'configure' mirroring in your DE, or you can possibly set it up directly in the Xorg conf too

or xrandr might write iut somewhere, but that's never happened for me

rlemon

yea. once we get the actual display we'll be using sourced, I'm going to move the xrandr stuff to the .xinitrc

djsmiley2k

:)

it mightr be obvious to you, but if it's complaining because X hasn't full started, just call a script with a sleep in it

rlemon

20:59

that feels like cheating

and very rigid

unless I sleep like 90 seconds

:P

djsmiley2k

:D

This a fun project, or a work thing?

bertieb

21:33

@djsmiley2k Ya, Android on my OP3

djsmiley2k

i bneli8eve so

settings -> power -> power settings -> ignore for these apps something something

bertieb

21:58

Power settings?

That's what I do when the app tells me to

Which makes me think that setting isn't permanent

Michael Frank

It's supposed to be permanent, but certain manufacturers like to "fiddle" with those settings.... Looking at you, Huawei

bertieb

Yeah

Didn't someone (Ave maybe?) link to a page that named and shamed?

ISTR OnePlus were on there

Also, remind me to stay the heck away from power saws
