It happened to me as well on my lenovo ideapad laptop when I upgraded from Xubuntu 19.10 to 20.04, and my 1366x768 resolution ended all garbled. Then, after a while googling for solutions (which there wew so few!), I came up with a weird but functional workaround: I opened the display window, selected the 1366x768 resolution, rotation: inverted and reflection: horizontal and vertical, then applied. Worked!

Already in 3.38.2. Still happening

So it’s not enough, maybe with xorg 1.20.10

Too bad I arrive so late, regarding i915, here my working _/etc/X11/xorg.conf.d/20-intel-graphics.conf_ is

```auto
Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   Option "TripleBuffer" "true"
   Option "TearFree" "true"
EndSection

```

Nothing about _AccelMethod_ or _SNA_ but _TripleBuffer_ - in case it might help someone…

Removing the AccelMethod option worked for me. Thanks.

As time goes by, there has been some updates ( 20.04 here ) regarding xorg-server, mesa and intel things recently.

Today my system runs without any _20-intel-graphics.conf_ file and so far so good…
