@derobert thanks m80!

For the info, not for the self-realization

Thanks @MichaelHomer

Turns out I just didn't know what I was doing.

POSIX destroying my life. I thought I was just a bad programmer and didn't know what I was doing.

Is this a Linux thing, or is Vim being a dick to me? wc -c and wc -m report X + 1 bytes, and on inspection of the content read via the final fgets call, I confirmed there's a newline present.

I have a slight issue/problem thing. I'm working on a project for uni, and we need to validate that a file containing text has exactly X bytes. I've handled the text processing, but for some reason the files are always 1 byte longer, even when I carefully type out each character. It appears that there's a gosh darned newline that vim appends when I save and exit the file, which means that everything always appears invalid because of a gosh darned newline.

That's a good idea!

@FaheemMitha I'm gonna try to make time to read the changelogs, maybe they addressed an Elan touchpad issue. Some things are still kooky. libinput is still wrong a bit, I still can't have my touchpad disabled on typing, and even if I wanted to get rid of the "area" touchpad functionality, it won't let me choose something like "left click only".

gotta re-read my question and see if all my issues are fixed.

@FaheemMitha So, dunno how it happened, but my mousepad appears to functioning normally again...big update last night with some Xorg stuff and some kernel stuff getting updated, guess it's fixed now, hopefully.

@cas Fedora 30

@terdon I didn't realize the answer to such a question would be so...undefined. Figured it'd be an "oh yea, it's always this" or a "check this environment variable"...should have learned by now that simple answers aren't common...

probably a dumb bet...

I was betting on being able to use character classes

In any case, I probably should have mentioned the regexp I was using: ^\+1[[:space:]]*$

So, it's a kinda "usually it's this, but depends" situation?

How do I determine the regexp library supplied by system?

I'm trying to use a regexp in less to find improperly formatted lines, but the ones I use with grep aren't working, I get an invalid pattern error. The manpage says:

Lol the Onion is gold. "Study: Pregnant Women Can Drink One Bottle Of Wine A Day If Fetus Can Hold Its Alcohol"

@FaheemMitha Yea, there are several EE and WW lines relating to Nvidia in the 50 lines I scrolled through out of about 860. How should I attach the log to my question? Get a pastebin link, or filter the doc for lines containing keywords like "input", "elan", etc.?

@derobert Thanks!

@FaheemMitha Are these "[ 9323.014]" things timestamps in the Xorg log? What do they correspond to? Seconds? Minutes? I'd love to know when log lines actually appeared in the log.

@FaheemMitha It might have happened around the time I was setting up my Nvidia GPU. I admittedly never payed attention and have no idea what could have changed, or if it was always logging to both places, etc.

@FaheemMitha Did not choose it. It used to log to /var/log/Xorg.DISPLAY.log

@FaheemMitha why?

Got it from this guy: unix.stackexchange.com/questions/453969/…

@FaheemMitha Turns out my Xorg logs are not for display 0, rather they are for display 1, and they are located in $HOME/.local/share/xorg, and there is an Xorg.1.log timestamped today.

I think the IntelliJ one should get deleted. 27 views in 5 months means that no one else has that issue.

I answered a few of my own questions that never saw any answers. Let me know if the self-answer looks good, or if the question should just get deleted: unix.stackexchange.com/questions/522752/…, unix.stackexchange.com/questions/510118/…, unix.stackexchange.com/questions/533745/….

@FaheemMitha Fedora Workstation 30.

@FaheemMitha multiple times within the last 7 days

@FaheemMitha I've only ever used startx occasionally. I've not started it Xplicitly (lol puns) in the recent past. I thought X was started automatically when the default.target symlink was set to the graphical target for systemd. I must admit a significant amount of ignorance about all of the pieces that go into displaying things on screen and tying together all the hardware to do that.

@FaheemMitha Yea, but what's even more suspicious is that it appears the log was last edited on 3 August. It is the Xorg.0.log. I'm guessing something happened to the X server when I was messing with Nvidia? Might explain why stuff isn't getting logged, but I'm not sure. Maybe I need to reinstall Xorg somehow...

@FaheemMitha This is my Xorg.0.log, which was last modified on 3 August 2019. pastebin.com/4fuWL2q0

What would the four buttons be? Right-click, left-click, middle-click, drag the mouse around? This is a buttonless touchpad.

I searched the output for mentions of "elan|Elan" but nothing came up

I'd never heard of dmidecode! The output looks really useful.

Came across this is in dmesg. It must have escaped copy/paste because I was using the touchpad: [ 1856.428680] elan_i2c 5-0015: failed to read report data: -6 Gonna add to the question.

I'm guessing part of the change is that I had not yet installed the Nvidia drivers and done everything to set up my dGPU as the old dump shows the Nvidia card didn't have any driver set. But it's odd that the "Display" field no longer has "x11", and the "driver" is set to "none" now. Literally no idea if this means anything...

An older version of this dump has Display: x11 server: Fedora Project X.org 1.20.5 driver: vesa unloaded: fbdev,modesetting

I just ran inxi -Fxmz and in the section for graphics, I have this line: Display: server: Fedora Project X.org 1.20.5 driver: none tty: N/A

@FaheemMitha You asked "do other laptops use this touchpad" I interpreted that as the touchpad model, but I'm guessing you just meant the manufacturer. I have no idea if the model would matter. My guess would be no, as the drivers probably have backwards compatibility for older models. I'm probably gonna go the route of trying to create Xorg configuration files for the touchpad.

All the output in my code blocks in the question just show some variation of "elan touchpad"

I've seen other questions about elan touchpads, but I'm not sure what this model is.

@FaheemMitha Ah, no. Built in touchpad

Pretty sure the line is no longer produced.
