I have installed xserver-xorg-video-ati_6.7.192-1ubuntu1 to help ubuntu choose which driver is the best for gutsy (the 6.6 or the 6.7) Unfortunately I discovered lots of problems in 3d apps: ppracer does not display images and fails to draw text. there are tons of line like this in the console output [driAllocateTexture:636] unable to allocate texture I tried to run compiz with them and the result is a mess. You can see the screenshot here http://ubuntuforums.org/attachment.php?attachmentid=41888&stc=1&thumb=1&d=1188308551

The texture space is probably too small, try reducing the maximum virtual size with the Virtual directive or Option "FBTexPercent" with values > 50. P.S. Looks like the screenshots can't be viewed without an account there, please just attach them here in the future.
I tried with a value of 70 with the same result. Should I increase it again? I will attach the screenshot here, sorry

(In reply to comment #4) > I tried with a value of 70 with the same result. Should I increase it again? You can try up to 90 or so, but also verify in the log file that it actually does increase the size of the texture area.
I've tried with 90, the same result. Xorg.0.log shows the call to that option, so it should be ok (**) RADEON(0): Option "FBTexPercent" "90"
(In reply to comment #8) > I've tried with 90, the same result. I suspect it may not actually be able to go beyond 50 with XAA. > Xorg.0.log shows the call to that option, so it should be ok > (**) RADEON(0): Option "FBTexPercent" "90" No, grep 'for textures' /var/log/Xorg.0.log
by default the driver allocates buffers for a 2560x2048 desktop. Add a virtual line to your the screen section of config to reduce the size of the desktop to free up more vram. e.g., Virtual 1400 1050
(II) RADEON(0): Will use 3904 kb for textures at offset 0x3c28000 I will also try with the option Virtual. But, well, an additional option should not be added, I mean, it worked with the previous driver version!
with virtual I don't have these problems anymore. What happened? I don't think it is normal!
(In reply to comment #12) > with virtual I don't have these problems anymore. > What happened? I don't think it is normal! > It is for the new driver. The problem is randr. We don't know what monitors may be attached when or whether a user may want to switch between single or multi-head, etc. As such we try and make a reasonable default desktop size to accommodate the largest number of users. If the default was 1400x1050 and you had a 1600x1200 monitor, your desktop wouldn't be big enough. All of these problems will go away when we finally get a decent memory manager, but we are not there yet. Right now we are still tweaking things trying to find the best middle ground until ttm lands.
In which version of the driver will we have a decent memory manager? 6.8 or in the far future? Well, anyway this is really a problem for users which do not have a video card with lots of ram (I have 64MB)
I have news. The option Virtual is not enough. See what happens now if I play supertux + compiz (see attachment)
