I've installed Ubuntu on my chrombook using crouton, so I can switch between OS's. However, the screen keeps flickering to chrome OS when I'm using Ubuntu. Does anybody know how this could be fixed? I saw somebody else on the blog who had the same problem so some help would really be appreciated!
@Seth I haven't switched over, but I'm not on mainline either... so it wouldn't be of any help to you. Did they switch over to Wayland on 16.04 mainline? If so, that could be part of it. Compositing not quite sending the right things to the GPU and sending too much to CPU
That's possible. It might be offloading some compositing to the CPU if it knows the intel driver isn't very good at it and expect that if you're running intel gpu, you chose a faster cpu.
I'm telling you, 3 more hours/2 hours before you're going to get tired. It's psychological. When you dread something, you don't get tired. Then avoidance kicks in about 2 hours before.
@jokerdino I wrote one of those about how Animal Farm could actually be construed as a greenpeace piece. My English teacher - "I think you were REALLY reaching on that one, but you supported your argument so well... I had to give it a pass even though it was a stretch."
I have multiple Linux CentOS servers that are scanned with the Google Webmaster Tools and when it finds some malicious code on my servers (shared/dedicated), the ranking of those site drops.
What I am looking for is a server scanner that scans .php, .js files and the likes for malware code, so ...
I am new to posting questions and answers on SE, although not new to using the various SE resources. I also get the need for questions and answers to be concise and accurate, we all need answers and quickly.
But purely to give me some direction for future answers what specifically was the reason...
@blade19899 OK, then the DNS you have in resolv.conf isn't working. Either the DNS service is down, nor the server is unreachable or something. If changing DNS servers fixes your problem, you know that the problem is with the DNS you are using.
@blade19899 No. I know next to nothing about networking. I also have no idea what server this is. The DNS server? The machine using the DNS server? Why don't you post a question?
@terdon 11 days without my main system. It feels so long time. My other HDs are in so bad shape that I have not wanted work further other projects. I am trying to copy-system here askubuntu.com/q/774138/25388 such that I will have copies of my systems for the future such that no such failure happens again.
I have no idea, but right now I have two Linux servers(CentOS 7.2.1511 (Core)) that are identical, but on one the server stopped connection to ipv6.
The following output is the same for both servers X and Y
dmesg | grep IPv6 [ 4.330627] IPv6: ADDRCONF(NETDEV_UP): eth0: link
is not read...
@terdon Yes, I know. But it is good to learn from it. Backups/clones of HDs are essential. I have cheated myself and not taken them responsibly so it is good time to learn to do it.
Yes, it is another thing that I learned. So I do not do it anymore. Just home-folder encryption. But still, they say that I should not store backups encrypted. I do not understand yet why.
@Masi because encryption implementation is as it is tricky and fragile piece of code, and if the code changes only so sligthly there is a possibility your encrypted backups are lost. that is the main reason for not making the backups encrypted
does anyone know how to add default entries in zenity forms??
zenity --entry=username --entry-text=severus works fine but zenity --forms --add-entry=username --entry-text=severus wont work :(. It is showing --entry-text is not supported for this dialog. Does anyone know the proper syntax ??
What do you care if it does overwrite it though? Your Kubuntu GRUB will be identical to your Ubuntu one. I guess they might change the themes but even if they do, just boot back into your original and run grub-install again.
@Seth Sure or on another partition or whatever. More to the point see above. What do you care whose bootloader you have?
@terdon aha! I didn't realize grub-install was a thing. alright, maybe I'll just roll with that. It's just a pain since it gets overwritten every kernel upgrade.
Boot into either Ubuntu and run
sudo update-grub
That should generate a new grub config file with your newly installed OS. It should appear next time you reboot.
If it doesn't, run this as well:
sudo grub-install /dev/sda
That will install grub in the MBR of your first hard drive. Change...
@Seth Huh? it might be update-grub2 nor something or grub-update. In any case, you can do it manually, it just runs grub-mkconfig -o /boot/grub.cfg and grub-install /dev/sda
@Seth Perhaps you were sharing the /boot partition? I guess you could always change the theme manually. Or just tell it to install grub to the USB as you said and be done with it
Does anybody know if I can set 16.04 up to open the Dash's application lens instead of the home lens as default when clicking on it, as well as with 4-finger-touchpad-tapping?
I've got a zenity form working, but I can't find any information on initializing the entries. The Zenity help manual webpage doesn't address the issue.
For example, the example from that webpage is
#!/bin/sh
zenity --forms --title="Add Friend" \
--text="Enter information about your friend." \
...
@SeverusTux alternatively, don't populate the fields, populate the variables instead. Something like this (using the example from the SO question you linked to):
#!/bin/sh
## Default values
default="John,Doe,jdoe@mail.com,05/14/2016"
zenity --forms --title="Add Friend" \
--text="Enter information about your friend." \
--separator="," \
--add-entry="First Name" \
--add-entry="Family Name" \
--add-entry="Email" \
--add-calendar="Birthday" >> addr.csv
case $? in
0)
echo "Friend added.";;
1)
echo "No friend added, using default values: $default"
echo "$default" >> addr.csv
;;
-1)
echo "An unexpected error has occurred."
The user won't see the values but you could change that with something like this:
zenity --forms --title="Add Friend" \
--text="Enter information about your friend." \
--separator="," \
--add-entry="First Name (def: John)" \
--add-entry="Family Name (def: Doe)" \
--add-entry="Email (def: jdoe@mail.com)" \
--add-calendar="Birthday (def: 05/14/2016)" >> addr.csv
@SeverusTux Sure, I was writing a comment to explain, but I will contimue here :)
@SeverusTux In the Unity Launcher, an application should only be represented by one icon (.desktop file). This should always be the same, and it should be the application's own launcher, with the correct keywords set and all. If you create multiple .desktop files, calling the application in their main command (first Exec= line)
, not only its appearance in the Launcher might get corrupted (new windows of the same app will also appear under the home-made icon), but keywords might be incorrect. Unclean practice.
@SeverusTux I bet you can, create a simple launcher, calling a folder in nautilus, or a terminal with options. Run it and then run the main application.
@SeverusTux The thing is, it is unpredictable, sometimes it works, sometimes it doesn't. On earlier Ubuntu versions, it practically went always wrong, but I guess Unity got smarter :)
