@randomuser Unfortunately it did not help. I'll probably update at some point.

2016-09-07 02:54:23 -0500 asked a question SELinux AVCDenials for abrt-hook-ccpp

For some time now I get the SELinux AVCDenials with the following details, which as far as I can tell are always the same:

SELinux is preventing abrt-hook-ccpp from getattr access on the file file.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that abrt-hook-ccpp should be allowed getattr access on the file file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

What can I do?

System giving me these popups for AVCDenial makes me feel like something isn't right in my system, which is annoying.

OS: Fedora 22, 64Bit

I don't really know what other info I should provide, because I couldn't figure out a pattern for the AVCDenials yet. However, it's almost always about that abrt-hook-ccpp.

Q: When did it happen?

A:

  • shortly after starting the Atom editor, when I right-clicked a file and chose to open with the Atom editor
  • (if I notice more, I'll add here)
2016-07-27 14:52:54 -0500 commented answer Remove Nvidia and Nouveau drivers without starting Fedora

I didn't install nvidia drivers using the repositories, I think. At least it says no packages marked for removal when I try that dnf remove.

2016-07-27 14:28:36 -0500 commented answer Remove Nvidia and Nouveau drivers without starting Fedora

But how can I do this? I cannot even get into a shell at the moment, with the different graphic card plugged in. I can only get to Grub, but don't know how to get into a shell, where I cut utter these commands. When I start with one of the entries, it'll load Fedora and show me a lot of text output, but will simply become non-responsive at "Stopping User Manager for UID 42".

2016-07-27 08:11:18 -0500 asked a question Remove Nvidia and Nouveau drivers without starting Fedora

My video card (GeForce 9800GTX) is damaged and I needed to take it out of my machine. The only other video card I have available now is a Radeon HD 6000something, so not an Nvidia card. The problem is, that there are still proprietary Nvidia drivers installed on the machine. I also have Nouveau drivers on it, but they are deactivated for now.

I am worried I might damage something, if I try to start my system with the Radeon card in it and the Nvidia drivers in place.

My Motherboard does NOT have an onBoard graphic chip and does NOT have a VGA port I could use when not having any video card build in (EVGA Nvidia nForce 780i SLI), so I need to use that Radeon card to get any picture on screen, afaik.

How can I remove the Nvidia drivers and possibly install the AMD drivers for the Radeon card, without damaging anything? (and get the system into a state, where I might install AMD drivers)

Other Infos:

  • Motherboard: Nvidia nForce 780i SLI
  • GPU: GeForce 9800 GTX
  • CPU: Q6600
  • RAM: 2x2Gb
  • OS: Fedora 22, 64 Bit

Update#1:

I managed to get into a shell by going into GRUB, then editing one of the entries, by pressing e on it and appending a 3 to the end of the line, which begins with something like linux16. This is supposed to let me boot into text only interface, as I read one other websites. Then I started that kernel by pressing ctrl + x as the GRUB editor tells you below the input area, when editing the entry. Then I spammed ctrl + alt + f2 to get into a shell. This was not possible before adding the 3 to that line in GRUB. Now I am in that shell, but I cannot install AMD-drivers, because of:

Failed to synchronize cache for repo 'fedora-HandBrake' from 'http://negativo17.org/repos/HandBrake/fedora-22/x86_64/': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried, disabling.

Last metadata expiration check performed 0:00:00 ago on Wed Jul 27 21:43:22 2016.
No package AMD-drivers available.

Update#2:

I was able to remove the nvidia drivers using nvidia-uninstall, which seemingly gets added, when you install nvidia drivers not from the repositories.

After that, I was able to boot into my normal GUI again. This seems to be working for now.

Update#3:

It seems there is already an open source driver installed on my machine for AMD cards:

:lsmod | egrep "amdgpu|radeon"

results in:

2016-05-04 08:16:19 -0500 commented answer create application icon/launcher -- LightTable

The answer is incomplete, you have to add #!/usr/bin/env xdg-open as a first line to make it work.

2016-05-04 08:16:18 -0500 commented answer Desktop Files not found

It was the #!/usr/bin/env xdg-open missing and the fact that there cannot be an empty line between #!/usr/bin/env xdg-open and the [Desktop Entry] line. Thanks!

2016-05-03 19:06:32 -0500 asked a question Desktop Files not found

I am running a Fedora 22 with Gnome 3. When I place .desktop files like the one here into my ~/.local/share/applications directory, they still don't show up when I type parts of the name of the application in the dash.

Is there anything special one needs to do to enable those desktop files?

2016-05-03 19:06:29 -0500 commented answer create application icon/launcher -- LightTable

This doesn't work for me. When I enter any part of "lighttable" in the dash (super, then typing) in Gnome 3, it still doesn't show me the launcher.

2016-04-30 19:39:46 -0500 commented question Random GUI Glitches and Freezes

I don't know how to downgrade single packages and I don't want to risk causing it again. journalctl -b doesn't go to the end of the file and I'd have to scroll a few hours to get there. I'll add the output of dmesg | grep error to the question.

2016-04-30 10:42:33 -0500 asked a question Random GUI Glitches and Freezes

In the last two days I had many seemingly random GUI freezes in my Fedora 22. At first I thought them to be related to the Vivaldi browser and switched to Firefox, which is also installed. But the freezes continued, so I assumed it was about flash videos on youtube. I installed an addon to always use the HTML 5 version on youtube. Still freezes continued. I downloaded the latest NVidia driver then and reinstalled that one (was already installed in that exact version), but even on run level 3 while finishing the installation of the nvidia drivers, I got the same graphic glitches I notices before I the GUI freezes. I'll try to describe the phenomenon:

  1. random pixels rush over the screen, disappear again or not and stay on it
  2. mouse pointer shortly freezes then unfreezes again
  3. then more random pixels and flickering occurs
  4. until finally the whole GUI is frozen
  5. I can still hear sounds from videos etc.

Sometimes I could log out with some key combination I tried: ctrl+alt+k or ctrl+shift+k or ctrl+shift+alt+k I just tried them all because I don't really know which one is correct. But when I logged in again, it took even less time for the issue to reappear and then I couldn't do anything at all, except pressing the reset button on my computer.

When I was on runlevel 3 installing the nvidia driver, I assume it cannot have been the drivers fault, as I started the system after doing: systemctl set-default multi-user.target and only had a terminal, no GUI. However instead of random pixels, I then for random characters on my screen, colored and in areas of the screen / terminal, where I didn't even get with the input of the terminal.

For now my system runs, but I cannot be sure if this doesn't happen again randomly at some point. I've build up some distrust to my Fedora 22 distro and I'd like to know how I can see any error messages or something for this phenomenon and if others have the same issues.

I already took a look at journalctl -e to see if anything nvidia stands out. Because usually nvidia is the problem if there is any problem on linux ... but so far I didn't see any error in there, that could cause these issues.

Note, that it only happened the last two days. I did also do dnf update, so maybe it's related to the updates 2 or 3 days ago (today: 30th of April 2016)?

Further Details

  • I have a Nvidia GeForce 9800 GTX.
  • Q6600 CPU
  • Fedora 22
  • 4GB RAM
  • uname -a gives: Linux localhost.localdomain 4.4.6-201.fc22.x86_64 #1 SMP Wed Mar 30 18:30:16 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

For more info just ask, don't know what else could be interesting for resolving the issue.
