Gather information about regression on some Intel GPU (Braswell, Kaby Lake)
Well, since Tails 3.12, many users have been complaining that they get the “Error starting GDM” issue, and finally I got answers confirming that there hardware were working fine with Tails 3.11, so that’s a regression.
Here is the list of affected GPU that were working fine with 3.11:
- Intel Corporation Atom/Celeron/Pentium Precessor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller [8086:22b1] (rev 35) - (2 reports)
- Intel Corporation 82915G/GV/940GL: integrated Graphics controller [8086:2582] (rev 04)
Here is the list of potential regression (not sure about 3.11 behavior):
- Integrated Graphics Controller [8086:0a16] (rev0b)
- Intel Corporation HD Graphics 630 [8086:591b] (rev 04) - (4
reports) → GDM fails to start in troubleshooting mode on 3.13.2;
with troubleshooting mode and
xorg-driver=modesetting
, it fails to start because/dev/dri/card0
does not exist (expected since troubleshooting mode setsnomodeset
; note that thenouveau
driver is also loaded - Intel Corporation UHD Graphics 620 [8086:5917] (rev 07) → GDM
fails to start in troubleshooting mode on 3.14.2 (3.14 booted fine);
fixed by passing either one of
xorg-driver=intel
orxorg-driver=modesetting
for one user; contradictory report that saysxorg-driver=modesetting
is not sufficient on the same hardware
And from the few users who answered back, none of the following workaround works:
