Bug Description
This affects both Ubuntu GNOME and Ubuntu Wily 20151017.1. The graphics are so badly garbled I can only file this bug on an unaffected OS where I've held back the update on just that one package to about Beta 1 status:
lance@lance-
xserver-
Installed: 2:2.99.917-1ubuntu1
Candidate: 2:2.99.
Version table:
2:
500 http://
*** 2:2.99.917-1ubuntu1 0
100 /var/lib/
I'll attach a picture of the garbled screen with the updated xserver-
The info provided by lspci may not be very helpful:
lance@lance-
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])
Subsystem: Intel Corporation Device 0025
Flags: bus master, fast devsel, latency 0, IRQ 27
Memory at d0000000 (64-bit, non-prefetchable) [size=4M]
Memory at c0000000 (64-bit, prefetchable) [size=256M]
I/O ports at f1c0 [size=8]
Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915
The tech specs show:
Internal Graphics:
• Intel ® GMA4500 onboard graphics subsystem with support for:
― Analog displays (VGA)
― Digital displays (DVI-D)
I'm just using VGA ATM.
Something else worth mentioning is this warning displayed while filing the bug report:
Your system is providing 3D via software rendering rather than hardware rendering. This is a compatibility mode which should display 3D graphics properly but the performance may be very poor. If the problem you're reporting is related to graphics performance, your real question may be why X didn't use hardware acceleration for your system.
I did try booting an earlier kernel to no avail, but holding back just this one update prevents the borkage.
