That is, is the problem specific to KMS, or is it in X? Also, can the backlight be restored if you change the brightness up/down after resume? In anyway, please give more information. For example, hwinfo --gfxcard output, Xorg.log and kernel messages after suspend/resume, etc. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The possible fix has been included in 4.0 kernel (commit 66c2b84b). If 4.0.x still doesn't work, it means a different bug, and it has to be informed to upstream bugzilla, too. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=841822 http://bugzilla.novell.com/show_bug.cgi?id=841822#c21 --- Comment #21 from Takashi Iwai --- (In reply to Darren Freeman from comment #20)

Old kernel version: 4.0.5-4.g56152db-desktop New kernel version: 4.0.5-1-desktop

Moved to Factory repo for the kernel only.

Still broken, but different.

Now, instead of seeing black, I see a flashing cursor in the top left, on a black background, followed by a whole bunch of garbage, much of which is flashing.

It looks like it's in a low-res text mode. About 28 characters tall. A whole bunch of similar custom characters, different colours and some of them flashing.

If I hit ctrl-alt-F1, I get a different screen. Still characters, only this time just a few green ones on black. I can then ctrl-alt-F7 back to the other screen. Back and forth, I can flip between the two broken screens.

So yes, there's probably a second bug here, and it's not fixed!

Also I just noticed that my laptop is a T41. It says so right under the screen.

Then could you rather update the information on upstream bugzilla entry so that upstream devs can work on it? https://bugzilla.kernel.org/show_bug.cgi?id=65141 Or fell free to create another bug report. Maybe bugzilla.freedesktop.org can catch more caution. -- You are receiving this mail because: You are on the CC list for the bug.
