[07:17] <alkisg> Hi, with an older i915 card (82Q963/Q965 Integrated Graphics Controller [8086:2992]) xorg freezes (mouse moves) and I'm getting these messages in dmesg:
[07:17] <alkisg> [   32.168374] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=1729 end=1665) time 3 us, min 894, max 899, scanline start 346, end 346
[07:17] <alkisg> Is there any i915.disable-something option that I could try, to make things work even if they become slow?
[07:18] <alkisg> (latest 20.04 stacks)
[07:35] <alkisg> Setting  `Option  "AccelMethod" "uxa"` makes the desktop work fine even though the dmesg errors keep appearing
[07:36] <alkisg> I also see: [  312.372825] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:37:pipe A] flip_done timed out, maybe uxa solves that one...
[07:57] <tjaalton> nomodeset
[08:01] <alkisg> tjaalton: it works that way, but with 640x480 :/
[08:02] <alkisg> I guess uxa + a bit of delay for the page flip lags is the best :)
[08:03] <alkisg> Thank hyou
[08:03] <alkisg> *you
[08:03] <tjaalton> or don't use -intel?
[08:03] <tjaalton> not sure if it does
[08:03] <alkisg> It fails with both driver intel and driver modesetting in xorg.conf (if that's what you're proposing)
[08:04] <tjaalton> ok
