intel graphics driver update causes artifacting skylake

Why is this important? Modesetting (which is itself a module in the X server) uses GLAMOR acceleration that is again a module INCLUDED in the X server, not like SNA externally provided by Intel DDX. Intel works pretty much ok, you have tearfree option that works etc.Īnother thing that maybe is overlooked by people advocating modesetting is that on Jessie (with backports or not) the X server is old compared to testing/sid. On Skylake Intel the modesetting driver is bad even on testing compared to intel's DDX - tearing everywhere, slow updates etc. I was using Backport kernel (4.3, 4.6, or 4.7 from jessie-backports), otherwise the system is using jessie (stable) distribution. I wonder if anyone of you ever experienced problem like what I described in this bug report. The problem would persist until I restart the X display. These should not have happened at any time, otherwise it is like a time bomb to the X display.

Instead of X keyboard becoming slow & responsive, the display itself becae very unresponsive after one of certain events was triggered-see the bug report for detail. Actually the bug report title was misleading. Some examples shown in the bug report include:Ī) running osd_cat plus gtk showing a pop-up notification on the screen cornerī) running xpdf to display a corrupt PDF fileĪfter that, the display would become many seconds late to update the content, which mainly noticed with text editing (like, characters not showing up in GUI terminal until 3-5 seconds). In brief, the X display will become unresponsive when certain legacy X software was invoked. 1) xbacklight not working was annoying, but not the worst problem.Ģ) The worst problem is the one I described in this bug that nobody responded to (so far):
