** Description changed: Binary package hint: xserver-xorg-video-neomagic Playing DVD or other video results in dropped frames and high CPU usage on a Neomagic NM2380 chip (MagicMedia 256XL+). The problem is evident in VLC and Totem. This was not the case in Hardy. The difference has been traced to the absence of the MTRR setting for video acceleration. This bug also exists in Jaunty and Karmic but I have not tested Intrepid. In Lucid (10.04): cat /proc/mtrr reg00: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back reg01: base=0x010000000 ( 256MB), size= 128MB, count=1: write-back In Hardy (8.04): cat /proc/mtrr reg00: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back reg01: base=0x010000000 ( 256MB), size= 128MB, count=1: write-back reg02: base=0x0fc000000 ( 4032MB), size= 8MB, count=1: write-combining Entering the command echo "base=0xfc000000 size=0x800000 type=write-combining" > /proc/mtrr in a terminal will set the MTRR but it will be reset at boot or when the X-server is restarted. + --- + Architecture: i386 + DistroRelease: Ubuntu 10.04 + InstallationMedia: Ubuntu 10.04 "Lucid Lynx" - Beta i386 (20100406.1) + Package: xserver-xorg-video-neomagic 1:1.2.4-2 + PackageArchitecture: i386 + ProcEnviron: + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcVersionSignature: Ubuntu 2.6.32-19.28-generic 2.6.32.10+drm33.1 + Tags: lucid + Uname: Linux 2.6.32-19-generic i686 + UnreportableReason: This is not a genuine Ubuntu package + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare ** Attachment added: "Dependencies.txt" http://launchpadlibrarian.net/44505817/Dependencies.txt -- Fails to set MTRR for 2D acceleration https://bugs.launchpad.net/bugs/564378 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
