Hello everybody. I have this strange problem, never had it before with the video card and fglrx.
I'm running Debian squeeze 2.6.26-2-amd64 on a HP 6715s laptop. I installed fglrx 9-2-2 via synaptic and I don't have a glitch with compiz.
However, whenever I unplug or plug ac power the screen goes black. Then, I have to Ctrl+Alt+F1 and back to F7 so I can get my regular screen.
Dmesg doesn't show any problems. My xorg.0.log shows this after a couple of plug/unplug. http://pastebin.com/f7fe54c92.
Thanks in advance.

Hi,

I'm having the same problem with Squeeze in my Dell laptop, same gfx card. Did you find a solution for this?

Regards.

No solution yet, but Ctrl+Alt+F1 and back to F7 every time. The screensaver doesn't work fine as well. I guess it has something to do with power management profiles, and some kind of inability to resume when the profile changes, but since I know little of this issues, I just gave up . It's strange it only happens to me with Debian, and not Ubuntu.
You are the first person I know that has this issue, and there are no other hints of this over Internet. Perhaps something missing?

Yes, that combination also works for me; but screensavers are ok here. The problem started for me after an update of my squeeze system, about a couple of weeks ago. Maybe a fglrx or Xorg bug. Haven't found any reference in the net either. I'll post it here if there is a solution.

Hi,

I solved the problem with my machine. It is a bug in fglrx it seems, as changing to the opensource radeon driver solves it. But the version of the driver and XOrg in Squeeze doesn't support direct rendering and 3D accel for the X1250. So I apt-pinned to the XOrg version in Unstable. Hope this helps you too.

Regards.

Thanks a lot emeck for sharing your achievements at tackling this problem.
As you, I'm basically on testing. I guess you mean the radeon driver with the radeonhd Xorg driver. I tried that on a previous Ubuntu installation, pulled and compiled the driver from git.
The problem is that the screen had various glitches (despite the fact that it did support 3d accel). Flickering and the sorts.
Have you experienced the same issues or is it working just fine for you (I know drivers in Ubuntu sometimes suck)? As I would break my fglrx driver with the upgrade (new Xorg doesn't support 1250 on fglrx, blame ATI) I would like to be sure I'm doing the right thing.
Did you also have to upgrade the kernel? I'm on 2.6.26. On the other hand, I'm willing to dump a closed source driver, as I would feel more calm with future upgrades. Right now, my kernel and Xorg packages are on hold.
Thanks.

You are welcome.

Actually, everithing is working now as when using fglrx previously (excepto s-video isn't working yet with radeon driver). The only "problem" is flickering with composite on when watching videos or TV, but as I do that in fullscreen turning off composite is ok (that happened with fglrx also). I'm using radeon, not radeonhd. As I understand, what is in radeonhd is being merged into radeon and the former will disappear at some point. Anyway, both seem to work ok; just noticed that font management is something different for radeonhd (fonts appear bigger).

I'm using:
kernel 2.6.30-1-amd64
xserver-xorg 7.4+4
xserver-xorg-video-radeon 6.12.3-1


Maybe you can try upgrading to kernel 2.6.30 keeping your current one and try radeon driver with the newer. fglrx-source won't compile right now with 2.6.30 so you can't create the modules for it but can go back to fglrx and 2.6.26 if you need to.
