Downgrading mesa fixes the problem. lspci: 00:02.0 VGA compatible controller : Intel Corporation HD Graphics 530 [8086:1912] (rev 06) Subsystem: ASUSTeK Computer Inc. HD Graphics 530 [1043:8694] Kernel modules: i915 Unfortunately I can't find a lot of useful information, here are some bits: * systemctl --failed says "gpu-manager" and "lightdm" have failed * Xorg.log is clean: https://termbin.com/6l2b * dmesg too: https://termbin.com/ip4e * It happens on lightdm/MATE, I don't know about Ubuntu GNOME. * If one runs `xinit` from ssh, it fails with: i965: Failed to submit batchbuffer: Invalid argument This is caused by mesa assuming that soft-pinning on GEN8+ is working since kernel 4.5, but in fact this issue wasn't fixed until 4.19.3. So a proper fix would be to backport commits from 4.19.3/4.20 to fix GTT sizes/pin flags, but that's left for future. [Test case] install fixed mesa or kernel, check that the regression is fixed [Regression potential] mesa: shouldn't be any, it just reverts the change to always soft-pin (TODO kernel: adds commits from upstream stable, which have been well tested upstream by now) To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/1815172/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : email@example.com Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
