[Bug 370441] Re: scrolling (and other effects) extremely slow
I was having poor video performance affecting: screen redraws, text entry in web browsers, desktop switching, window switching/selection, and much more. My laptop felt like it was filled with glue ;) I'm running a Sharp MM-20 (yes it's old!). dmesg reports my video chipset as: VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY My 9.04 install was performed clean from the 9.04 Alternate Install CD (not upgraded). No xorg.conf file was created by default, so in order to apply the changes referenced in the original bug report, I had to manually create an xorg.conf file. So I created a bare bones config file. contents of my /etc/X11/xorg.conf: Section Device Identifier ATI Radeon Driver ati Option AccelMethod EXA Option MigrationHeuristic greedy Option AccelDFS true Option EnablePageFlip true Option EnableDepthMoves true EndSection This resulted in much snappier redraws and better overall video performance. I also noticed CPU consumed by X drop from around 20-30% down to 5% after the change. I recommend that this be investigated further. Also, it may be prudent to have an xorg.conf file created by default for systems with this video chipset. I sense that by not having an xorg.conf, we are exposing a lot of users to floating settings and possible performance issues. -- scrolling (and other effects) extremely slow https://bugs.launchpad.net/bugs/370441 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

I had the same problem after a clean install of Jaunty on my Sony Vaio PCG-Z1RMP (ATI Radeon Mobility M6 LY.) ~30% Xorg CPU usage when just running top in a default size gnome-terminal. Using Klaas' xorg.conf brought my Xorg's CPU usage down to ~2%. Thanks Klaas! :) -- scrolling (and other effects) extremely slow https://bugs.launchpad.net/bugs/370441 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
