Bug Description

Binary package hint: xorg

When switching users in Lucid, often X will freeze up and just give me a black screen with blinking cursor. When I try to go to the current session with Ctrl+Alt+F7,8,9,etc. I either get black, distorted or a non-responsive unlock screen.

Hi Alwin Garside,
radeontool can be used to assist in debugging this issue. To install it from the command line, use this command:

sudo apt-get install radeontool

After installing it, you run it like this:

sudo radeontool regmatch '*' > regdump_good.txt
sudo radeontool regmatch '*' > regdump_broke.txt

Run it two times. Once when you have a working screen (for any driver), and once in the broken case (either from the tty console or logged into the sick box remotely). Attach both of those to this bug report, and we can then forward this issue upstream. Thanks ahead of time!

Is this related to #546578 perhaps?

Bryce Harrington (bryce) wrote on 2010-04-16:

Ernst, seems like a good guess. The way to test is to see if this command causes the screen to restore:

xgamma -gamma 1.0

Alwin, could you try seeing if the above gets the system back?

If that works around the black screen, then yeah we can set this as a dupe of #546578.

Running this command:
xgamma -display :0 -gamma 1.0

Indeed fixes the problem. Marking this as a duplicate of #546578

Alwin Garside, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

luigiburdo, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.
