See https://askubuntu.com/questions/1039189/today-i-got-an-update-and- graphics-are-not-working-right-on-ubuntu-16-04/1040545#1040545 for some other users with the same issue This regression was introduced by upstream commit dc911f5bd8aa. A revert of this commit fixes this bug. Upstream has already reverted this commit in drm-tip tree and cc'd it to upstream stable. However, the revert has not landed in mainline or stable yet, so it is being sent as a SAUCE patch. The revert is also needed in Bionic. However, the Bionic revert is slightly differant, so it will be SRU'd separately. == Fix == UBUNTU: SAUCE: Revert "drm/i915/edp: Allow alternate fixed mode for eDP if available." == Regression Potential == Low. This revert is to fix a current regression. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. After update to Kernel 4.13-43 the intel graphics seem to really lag - especially noticeable in apps which are using vsync, which, at least on my system, locks to 40fps unlike the previous kernel I have installed (4.13-41) which locks at a steady 60fps.
