Public bug reported: Binary package hint: x11-xserver-utils
xrandr does not detect that it can do dual 1680x1050 for office tasks on my ATI video card. It normally sees VGA-1 as being limited to 1360x768. I can get both screns to a higher resolution using this command : xrandr --addmode VGA-1 1680x1050 xrandr --output VGA-0 --mode 1680x1050 xrandr --output VGA-1 --mode 1680x1050 xrandr --output VGA-1 --left-of VGA-0 Although Video does not work well on the right screen at this resolution, normal office tasks ( spreadsheet, firefox, terminal, solitaire etc... ) all work very well. Therefore I believe that a bug exists in the detection of supported resolutions on my video card. This applies to Lucid Lynx. Any earlier Ubuntu can not handle the above resolutions on my video cards. It would be nice if you fixed the resolution detection. 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AR [Radeon 9600] Subsystem: ATI Technologies Inc Device 4772 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at e8000000 (32-bit, prefetchable) [size=128M] I/O ports at a800 [size=256] Memory at fe9f0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at fe9c0000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: radeon Kernel modules: radeonfb, radeon 01:00.1 Display controller: ATI Technologies Inc RV350 AR [Radeon 9600] (Secondary) Subsystem: ATI Technologies Inc Device 4773 Flags: bus master, 66MHz, medium devsel, latency 64 Memory at e0000000 (32-bit, prefetchable) [size=128M] Memory at fe9e0000 (32-bit, non-prefetchable) [size=64K] Capabilities: <access denied> ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: x11-xserver-utils 7.5+1ubuntu2 ProcVersionSignature: Ubuntu 2.6.32-21.32-generic-pae 2.6.32.11+drm33.2 Uname: Linux 2.6.32-21-generic-pae i686 Architecture: i386 Date: Tue May 4 16:20:58 2010 DkmsStatus: Error: [Errno 2] No such file or directory EcryptfsInUse: Yes InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release i386 (20100429) MachineType: HP Pavilion 061 D7222E-ABA A350Y ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-21-generic-pae root=UUID=9ec251d7-f543-46e6-aaab-b78faf6ab37e ro quiet splash ProcEnviron: LANG=en_CA.utf8 SHELL=/bin/bash SourcePackage: x11-xserver-utils dmi.bios.date: 04/27/2004 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 3.25 dmi.board.name: Stingray dmi.board.vendor: ASUSTeK Computer INC. dmi.board.version: 1.xx dmi.chassis.asset.tag: Asset-1234567890 dmi.chassis.type: 3 dmi.chassis.vendor: Chassis Manufacture dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr3.25:bd04/27/2004:svnHPPavilion061:pnD7222E-ABAA350Y:pvr03p1211RE101STING10:rvnASUSTeKComputerINC.:rnStingray:rvr1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: dmi.product.name: D7222E-ABA A350Y dmi.product.version: 03p1211RE101STING10 dmi.sys.vendor: HP Pavilion 061 glxinfo: Error: [Errno 2] No such file or directory system: distro: Ubuntu codename: lucid architecture: i686 kernel: 2.6.32-21-generic-pae ** Affects: x11-xserver-utils (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 lucid -- ati dual head high resolution https://bugs.launchpad.net/bugs/575393 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
