Created attachment 572008 [details] Xorg.0.log There appears to be a bad interaction between recent kernels (>=linux-4.19.27) and xserver. I'm seeing it on Gentoo, but it has already been reported on Arch, Fedora, and other distributions, as well as Xorg. According to tickets, it appears that kernel and xorg developers are trying to pass the buck to the other, leaving it up to distributions to handle patches themselves. Xorg ticket: https://gitlab.freedesktop.org/xorg/xserver/issues/542 Arch ticket: https://bbs.archlinux.org/viewtopic.php?id=244624 Symptom: X does not start properly and the screen fails to initialize. Xorg.0.log attached. Pertinent bits: [ 216.756] (EE) modeset(0): failed to set mode: Invalid argument [ 216.756] (EE) Fatal server error: [ 216.756] (EE) EnterVT failed for screen 0 Hardware (using i965 driver): 00:02.0 VGA compatible controller: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller (rev 21)
Same here: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) I switched from mesa driver back to xf86-video-intel and I can get into my desktop again. But unfortunately I now face problems with a black screen when reenabling a screen after screen blanking (energy saving). I have to switch to another VT and back to get it properly redrawn. Both issues (EnterVT failed with mesa, black screen after reactivating blanked screen) go away with my last used linux-4.19.23.
Looks like the revert of the kernel patch is in 5.1 and other stable trees.
