Intrepid: Elisa + fglrx distorted graphics

[Wouter Stomp]

Binary package hint: xorg-driver-fglrx

On intrepid, running elisa with the fglrx ati driver gives a distorted screen. See the attached screenshot.

This is with an ATI HD 3200 graphics card.

[Philippe Normand (philn)]

This looks like a driver issue. How other OpenGL apps work?

[Wouter Stomp (wouterstomp-deactivatedaccount)]

The opengl screensavers show allright.

[Tormod Volden (tormodvolden)]

What does it look like with the open-source -ati drivers?

[Wouter Stomp (wouterstomp-deactivatedaccount)]

With open source ATI the graphics are as they should be (but painfully slow though, elisa is really unusable that way). Same for the opengl screensavers.

[Tormod Volden (tormodvolden)]

Sounds like hardware 3D acceleration is not working with the open-source driver, and software rendering is used. I think your card is R600-based and 3D is work-in-progress.

[Wouter Stomp (wouterstomp-deactivatedaccount)]

Yes, I know that, and I would be very happy once that fully works. But the bug is with fglrx, but I guess it is not very likely to get fixed as it is closed source. Or are bugs like these forwarded to ati somehow? Is it useful at all to report bugs here against the fglrx driver?

[Loïc Minier (lool)]

Are you using compiz?

[Wouter Stomp (wouterstomp-deactivatedaccount)]

Yes, but it I get the same results both with compiz enabled and disabled.

[Tormod Volden (tormodvolden)]

Wouter, yes, it is useful to report fglrx bugs here. If only for other users who experience the issue to know that the problem is in the fglrx driver. And to document the trouble with this closed-source driver. And track any workarounds available or fixes in newer releases.

I have this bug too, but it is a little bit confusing.
The screen is only in fullscreen that mess of colors.
If I switch with the "f" key to window mode, everything runs fine!

Hi wouterstomp,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

[JanCR (jc-reehuis)]

This is the output of "lspci -vvnn"

[JanCR (jc-reehuis)]

My xorg.conf.

[JanCR (jc-reehuis)]

The Xorg.0.log.

[JanCR (jc-reehuis)]

It has to be a problem in ATI graficcard and OpenGL rendering.
I have the same distorted grafic in mythtv menu when i use OpenGL as theme painter.
When i change it to Qt as theme painter, everything in mythtv menu is going alright.

[Jens Christian (jc-westly)]

I have the same problem with XBMC and with Boxee using the proprietary catalyst 8.11 beta driver included with intrepid.

[Bryce Harrington (bryce)]

-fglrx does not yet support Compiz + OpenGL (e.g. see bug 179042).

We'll focus this bug only on elisa + fglrx with no Compiz loaded (as per comment #10).

Wouter, I do report some bugs upstream to AMD, however we must have complete info and steps to reproduce before we forward them. We're still waiting on you to provide your Xorg.0.log, lspci -vvnn, and xorg.conf.

[Wouter Stomp (wouterstomp-deactivatedaccount)]

Yes, sorry for the delay but I have no internet at home currently.

[Reported to AMD]

[Mario Limonciello (superm1)]

For some additional data, this happens in mythtv too if you choose the opengl menu painter.

[Mario Limonciello (superm1)]

I believe this may be a duplicate of bug 289628 (AMD EPR 257842)

[Igor Cota (igor-cota)]

There seems to be a workaround for this bug.

Simply start elisa or myth as a superuser (sudo or gksudo) and the fullscreen corruptions are gone. Weird, innit?

[Wouter Stomp (wouterstomp-deactivatedaccount)]

Yes, I can confirm that using sudo it works perfectly.
