You have been subscribed to a public bug: Hardware configuration: AMD Athlon 64 x2 3800+ on MSI K9N Platinum motherboard (NForce 570 chipset), 5Gb RAM installed. Video card is ATI x1300.
Software: 1. Ubuntu 9.04 with default install. It uses by default opensource 3D radeon driver for ATI x1300 and AMD dropped support for these cards in recent proprietary drivers. 2. Nexuiz 2.5 game (OpenSource, you can download it free of charge at http://alientrap.org/nexuiz/) To reproduce: Try to play Nexuiz for some time on some system with ATI x1300 card+OpenSource ATI driver. Results: 1) With default settings 3D is pretty slow compared to proprietary driver (you can lower default setting to cope with this). 2) System usually hangs after several minutes of playing Nexuiz. Expected: 1) Decent 3D performance 2) In no event driver should cause deadlocks. Note: This bug seems to be quite similar to bug 237080 (https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/237080) AMD had fixed this problem and their proprietary drivers no longer haves this issue. However OpenSource driver still haves similar problem. Note: This time I did not detected any avaialble crash dumps or smth like this. System just hangs, no extra data written to logs. Looks like kernel debugging guru needed and I'm not yet one of these, unfortunately. ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: New -- ATI: open-source driver could hang in some 3D applications. https://bugs.edge.launchpad.net/bugs/377605 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
