Issues with an Older Computer
I put together an old Pentium 4 system with an ATI 9250 AGP card hoping to use it as a development/test box. I have OpenGL working, to some extent, using the Radeon driver with KMS. At least
glxinfo | grep rendering
direct rendering: Yes
Nevertheless, the system boots into Gnome Classic even when Ubuntu is selected. The compiz configuration looks like Unity should run but it does not. It looks Like I won’t be able to use that system to play with Unity.
I wasn’t able to get Gnome 3 working from the Gnome3 team’s PPA on the box either. It seemed to install okay, and booted to the login screen but the actual login failed. The ppa-purge program worked fine though so I didn’t have to reinstall the system from scratch.
