Package: src:linux Version: 4.16.16-2 Severity: important Problem occurs with vmlinuz-4.16.0-2-amd64 No problem in vmlinuz-4.15.0-3-amd64
Problem occurs if user puts xrandr --output LVDS-1 --mode 1024x576 in his ~/.xsession file. Problem doesn't occur if user just invokes xrandr --output LVDS-1 --mode 1024x576 from the command line in an xterm. Problem is vblank wait timed out on crtc 0 [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:37:pipe A] flip_done timed out WARNING: CPU: 0 PID: 671 at /build/linux-hny3SU/linux-4.16.5/drivers/gpu/drm/drm_vblank.c:1073 drm_wait_one_vblank+0x16e/0x180 [drm] Using video=SVIDEO-1:d doesn't help.
