Debian 12 with XFCE Debian 13 with XFCE Ubuntu with XFCE Two different Nvidia RTX 4060 GPUs nouveau Nvidia proprietary driver versions 580.76, 580.105, 595.112
I built 3 identical PC's for one client, all three got RTX4060 graphics cards, Debian with XFCE, AMD Ryzen 9 7900X CPU, 64Gb RAM. The first two work flawlessly. This one....
One thing I pinned down so far, while running nouveau, hdmi works great, but DisplayPort does not: When I connect using dp cable, once the monitor sleeps, there is no bringing it up unless I ssh in and reset the dp port. For example, I can change the Hz, the monitor lights right up: nwe@pc01:~$ sudo env DISPLAY=:1 XAUTHORITY=/run/lightdm/root/:1 xrandr --output DP-4 --mode 1920x1080 --rate 60 nwe@pc01:~$ sudo env DISPLAY=:1 XAUTHORITY=/run/lightdm/root/:1 xrandr --output DP-4 --mode 1920x1080 --rate 180 it normally auto-detects to 180 Hz. So if it was running and I let it sleep, or I lock the screen (and my client insists on having screen lock feature), I try to wake it, nothing visible, no backlight on. I ssh in and switch to 60 Hz and it comes right up. Other way around works too: if I left it at 60Hz, switching to 180 lights it up. Setting the pre-existing Hz like say 180HZ -> 180HZ seems to be a no-op, nothing happens.
Hmm, the other two PC's with no problem, are running HDMI monitors. I could just tell them to replace their DP monitor, but first I want to try solving this mystery.
Now I installed Nvidia driver 595.112 and am investigating some more. That behaves slightly different, I get the login screen just fine, upon login I see just the mouse pointer on a dark screen with the backlight lit. The mouse pointer moves with the mouse.
Trying more things here... by the way: nwe@pc01:~$ sudo inxi -GSa System:Host: pc01 Kernel: 6.12.115+deb13.1-amd64 arch: x86_64 bits: 64 compiler: gcc v: 14.2.0 clocksource: tsc avail: hpet,acpi_pm parameters: BOOT_IMAGE=/vmlinuz-6.12.115+deb13.1-amd64
