I can confirm these performance issues, I have exactly the card as original poster:
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility U1 Just did upgrade from 9.10. My laptop is Compaq Evo N1015v. However with 9.10 I had problems with booting as it always hang on black sreen and started only when I booted in recovery and then after logging in started gdm by typing sudo start gdm. By default compiz effects were enabled which caused artifacts. 10.04 does not have any of those problems, but the performance is bad. -- [RS100] desktop became slow after upgrading to Lucid https://bugs.launchpad.net/bugs/544496 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
