[Bug 56692] Re: Radeon Mobility 7500: poor 2D performance, abysmal 3D performance
Some recent update fixed the 2D performance. It's still not as good as under Windows but now it's acceptable. The 3D problem remains, though... It might have to do with the following error message I get when starting GL apps: libGL warning: 3D driver claims to not support visual 0x4b Searching for this leads to an X.org bug report: https://bugs.freedesktop.org/show_bug.cgi?id=6624 There it is hinted that this might be a general DRI/Mesa bug since Intel chips are also affected. I'm setting this bug to Confirmed because several people on that bug have the same problem. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Unconfirmed = Confirmed ** Bug watch added: Freedesktop Bugzilla #6624 https://bugs.freedesktop.org/show_bug.cgi?id=6624 ** Also affects: xorg-server (upstream) via https://bugs.freedesktop.org/show_bug.cgi?id=6624 Importance: Unknown Status: Unknown ** Changed in: xserver-xorg-video-ati (Ubuntu) Sourcepackagename: xserver-xorg-video-ati = xorg-server -- Radeon Mobility 7500: poor 2D performance, abysmal 3D performance https://launchpad.net/bugs/56692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Mika, do you know what driver you are using ? vesa or radeon ? I do have a radeon mobility U1 (~ radeon 7000), and 2D performances are acceptable. I don't have any trouble when I move windows... -- Radeon Mobility 7500: poor 2D performance, abysmal 3D performance https://launchpad.net/bugs/56692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Jeremy, I'm using the radeon driver of course. :) I've attached my xorg.conf for reference. It's the default with the addition of the Options mentioned above. Perhaps one could call the 2D performance acceptable, it certainly is usable. But when I see what this card can do under Windows then the results on Linux are certainly disappointing, to say the least. On my girlfriend's computer which has a Geforce2 MX in it (using the closed-source nVidia drivers), half the RAM and a slower processor, working with Ubuntu is a lot more fun than on my laptop... -- Radeon Mobility 7500: poor 2D performance, abysmal 3D performance https://launchpad.net/bugs/56692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Have you looked at logs from Xorg server ? maybe some troubles are reported in it.

I see a [resume] line by the end of the file. Does the problem happen after a suspend / resume ?

No. The performance is the same befor suspending. -- Radeon Mobility 7500: poor 2D performance, abysmal 3D performance https://launchpad.net/bugs/56692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
