I have ubuntu 12.04 64-bit system, when i run glxinfo i see some strange error about indirect rendering and failed to load some lib32/dri/swrast_dri libraries.

Any idea what is going on?

please let me know if i can enhance the relevant information provided in this question

However, i did a search for that library and it is somewhere else:

$ locate swrast_dri.so
/usr/lib/x86_64-linux-gnu/dri/swrast_dri.so

I solved this by uninstalling the old one:

sudo /usr/share/ati/amd-uninstall.sh --force

then rebooted the machine, then installed latest 12.10 version

rebooted again (who said that in linux you don't have to reboot?)

and now the context is direct

You get two errors there: first it cant load /usr/lib/dri/swrast_dri.so and it can't load /usr/lib32/dri/swrast_dri.so failed also. To fix the first you can try to make a symbolic link to make the location it needs points to the real location of the files:

sudo ln -s  /usr/lib/x86_64-linux-gnu/dri /usr/lib/dri

I don't know if this is the best way, but if it doesn work you can delete the symlink created

sudo rm /usr/lib/dri

The next error seems to be related to the fact it cannot find the 32bit version of that libraries. You can try to install it using (libgl1-mesa-dri is the package that provides that file in my system):

sudo apt-get install libgl1-mesa-dri:i386

Hope this helps.

i just did install libgl1-mesa-dri:i386, but the only library in that folder is /usr/lib32/dri/fglrx_dri.so; swrast_dri.so is still missing. Not sure if i should symlink it to the x86_64 version –  lurscher Dec 3 '12 at 15:29
    
that's weird, in 12.10 that package installs that file in /usr/lib/i386-linux-gnu/dri/. You can try using apt-file search swrast_dri.so to see which packages provide it in your system. –  Salem Dec 3 '12 at 15:38
    
1st row: libgl1-mesa-dri: /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so 2nd row: libgl1-mesa-dri-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/dri/swrast_dri.so –  lurscher Dec 3 '12 at 15:46
    
i just downloaded the 12.04 version of libgl1-mesa-dri:i386 and yes, that file is present in the same place as 12.10 (/usr/lib/i386-linux-gnu/dri/). Check again –  Salem Dec 3 '12 at 16:34
    
the library is there! so i just need to make a symlink to the other path.. –  lurscher Dec 3 '12 at 16:43
