Package: xserver-xorg-video-nvidia Version: 319.76-1 Severity: important Dear Maintainer, I installed the nvidia proprietary driver along with its dependencies and recommended packages. I then activated SELinux in permissive mode and with the default policy. When logging in to the LXDE desktop, applications such as Openbox, LXClipboard, LXTerminal have a very high CPU usage (40% each), leading to a 100% CPU usage on both cores. The mentioned applications and other GUI applications are also unusable, as they do not appear. Purging all the packages and reinstalling them after SELinux activation did not solve the issue. Running the "restorecon -Rv /" command did not solve the problem. Blacklisting the nvidia module did not solve the problem.
Purging all the packages and using Nouveau instead solved the problem. No specific messages are visible in the audit log - only AVC Denials about systemd-logind. Thank you for investigating this issue ###### /etc/selinux/config ################## # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded.
