Hello, I see a constant 30% CPU usage in this particular xorg process: /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3 With some perf I have found that most of the time is spent on: - 32,91% 32,65% [v…

In my case, with the Dell Inspiron 7610, this is not the case - I am linking to a Linux kernel perf trace (rendered through, effectively, a Chrome flamegraph) which demonstrates very clearly that there are not errors the nvidia driver keeps spamming the VDSO for getting time - apparently in an att…

For me, your info just confirms that this a SystemD issue. I believe they call this behaviour progress not a bug. Multiple patches that down stream Distro’s havent handled well. It’s a mess. The impression I get is SystemD /Kernel Dev’s are playing Simon Says and everyone is scrambling to catch u…

This thread conflates a number of issues: The starting post had very obvious problems visible in the X log (see their Nvidia bug report attachment). Then people jumped in and said “my CPU is high”; I suspect that for many of these people the root cause is not found in the X log, but elsewhere. I …

Lenovo T15 Gen 1, problem is highly visible and it hurts a lot. Arch Linux, no Gnome and other garbage, just XOrg and i3wm. I believe that the laptop’s monitor is connected to the internal eDP-1 output while all other outputs are connected to nVidia GPU. The problem is equally reproducible with the …

FWIW, strace will only show the problem, IIRC, if the VDSO for the clock_gettime is not used. If you see this via strace, your CPU load will be even higher compared to systems where the VDSO is used.

Wonder if this issue has anything to do with it: [image] [515.65.01] D-Bus gets hammered on Linux kernel 5.18.18 Linux I’m on Fedora Workstation 36 and I’ve noticed that with kernel 5.18.18-200.fc36.x86_64 and Nvidia drivers 515.65.01, D-Bus gets absolutely ha…

No, checked with dbus-monitor, no traffic. dbus daemon is also sitting nearly idle.

No the systemd service and the X11 driver are two totally distinct things.

Hi, I would like to share my “workaround” lets go: my bios is mshybrid (nvidia optimus) prime-select on-demand I inserted into 70-uaccess.rules (udev), affet this line # DRI video devices SUBSYSTEM==“drm”, KERNEL==“fb0”, TAG+=“uaccess” ← avoid built-in monitor glitches when nvidia is set …

Without primary gpu yes (option), (xvidtune -show) [this command show up wrong info] steam game champions_of_regnum suffers from use right resolution (ignore external display default resolution), even the game launched with env primeoffload or vgaswitcherooctl (vgaswitcherooctl launch %command%) :…
