[Dell Latitude 2110] Garbled display after restore from hibernation

[Daniel Manrique]

Steps to reproduce:
- Put the system into hibernation.
- Press power button to restart and restore from hibernation.

Expected result:
- System restores correctly and display is usable

Actual result:
- The left 3/4 of the screen is black (or black with some miscellaneous garbling). To restore a functioning display, one has to put the system into sleep (for instance, by closing the lid), and on resuming from suspend, the display is restored correctly.

I tried grabbing a screenshot but the screenshot doesn't show the corruption or garbling on the screen. Also of note, the mouse pointer is visible even in the black portion of the screen.

This was tested to occur on Natty with 2.6.38-8 kernel, also with a 2.6.35-28 kernel from Maverick (to rule out a regression) and a mainline kernel from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2011-04-08-natty/linux-image-2.6.39-999-generic_2.6.39-999.201104080911_i386.deb

I'll attach a picture in a few minutes.

I tested Ubuntu 10.04 on this system (kernel 2.6.32-28.55), this kernel hibernates correctly and restores the screen without issues. Tagging with regression.

Assigning to the Platform QA team.
Medium importance, as the hibernate option will be hidden in Natty.

Daniel, as 2.6.32 works, would be great if you could test mainline builds from http://kernel.ubuntu.com/~kernel-ppa/mainline/, beginning with 2.6.32 and testing each later version, to isolate in which version the bug started to show up. It may help later to isolate the issue, or be a good starting point for a bisect.

Oops, just realized I'd neglected to attach the promised picture. Notice the cursor happily gliding over the black area of the screen, which doesn't redraw. The top bar on the black area on the screen is actually some garbly noise, not the actual panel.

I'll update on Monday with results on mainline build testing.

Thanks!

This looks the same as bug #745304 -- same graphics chipset, same sort of corruption. Marking as a duplicate.

[Carl Milette (carl-milette)]

the kernel 2.6.38-9 from proposed fixes the problem on three Dell Latitude 2110, one Dell Mini 10 and one Acer Aspire One ZG8 that were affected by this bug
