I have just installed Fedora on my computer, and got some very big graphic glitches. Here is the thing :

1/ I installed Fedora and noticed there was no sound on HDMI, so I decided to install the amd proprietary drivers to see if it changed anything (back on windows the hdmi sound was linked to my graphic driver so...)

2/ Restarting my computer, I had a black screen instead of the login screen. Couldn't switch to console mode either.

3/ I used grub to boot in console mode, and uninstalled the catalyst driver I just installed

4/ Back to Fedora, working fine as before, but enormous graphic glitches : Every system icon/font is completely destroyed, with random white pixels everywhere. It happens on the top bar, and also on every image/text when I activate the menu (windows key. I don't know how it is called). I looks like that on the topbar (couldn't make a screenshot of the menu, but it's the same on all the screen)

5/ I learned that there was a default amd driver (the free drivers) I tried to uninstall them just to see. Fedora worked but with a gray screen, so I reinstalled these default drivers. At this point I am supposed to have the original drivers that were on my system after Fedora's installation, but the glitches are still there :(

6/ I checked /var/log/messages to see what's up. There is an enormous amount of GL errors like that :

Oct 17 22:13:38 localhost /etc/gdm/Xsession[1108]: (gnome-shell:1256): Cogl-WARNING **: ./driver/gl/cogl-framebuffer-gl.c:615: GL error (1282): Invalid operation

Just to check, I tried to launch a movie on xbmc, it worked perfectly fine both on windowed and full screen mode, so I guess the graphic card works with Fedora, there is just something weird happening between it and gnome.

Sorry for the long post, I prefer to say any information I could find

Ok I've solved the problem. Short answer : Update to the latest version (Schrödinger's cat) and activate radeon audio in the grub 2 config by appending radeon.audio=1 to GRUB_CMDLINE_LINUX in /etc/default/grub (hdmi audio is desactivated by default)

Long answer :

I tried to download a Fedora 18 iso and launched the live CD, same glitches (except that strangely enough, they were tainted in a brown color instead of white).

I then remembered my Fedora 19 iso for somewhat old (a few weeks/months) so I checked for update and installed Schrödinger's cat (which I guess is a sort of major stable release), it seems that everything is working fine so far. Then I solved the audio problem by activating the hdmi audio in the grub conf.

There were no solution for me. Using fglrx doesn't work because the latest driver for the latest Xorg ist beta and not stable to use.

Running Fedora 18 were my solution.

I'm sorry for this, but ATI is just that slow while developing drivers for Linux.
