Public bug reported: Binary package hint: xorg
Briefly, I installed 10.04 from CD on older PC, was able to log into my account but desktop did not display panels at top or bottom of screen, so I could not launch any apps via GUI. Tried various things, finally got it to display panels, now everything seems to be working except that there are vertical strips about 3cm apart, seem to be 1-2 pixels wide, that rapidly flicker. Would like to eliminate strips and flicker. Here is more detail. Machine is custom made, about 8 years old, 512MB ram, 40GB hard drive. Since I couldn't launch anything with the GUI, I opened CLI terminal and determined the following. I ran lspci, found out this about the video controller: VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 02) Monitor is Philips 190B (flat screen). I looked up specs on the web, and found this: Horiz Freq: 30-83 Khz Vert Freq: 56-75 Hz recommended mode: 1280x1024 @ 60Hz Then I executed: sudo DISPLAY=:0.0 xrandr -q: got this output: Screen 0: minimum 640 x 400, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 60.0* 75.0 1280x960 60.0 1152x864 75.0 70.0 60.0 1024x768 75.0 70.0 60.0 832x624 75.0 800x600 75.0 72.0 60.0 56.0 640x480 75.0 73.0 67.0 60.0 720x400 70.0 Then I found a sample xorg.conf file on the web, installed it, and tried again. I'm not an expert at this. This time I did get the panels at the top and bottom of the screen, everything seems ok except for the vertical, blinking strips which are rather distracting. So I read man xorg.conf and tried to put more specific details in the xorg.conf file. I did this one step at a time, testing each step, but never managed to get rid of vertical strips. My final xorg.conf file is this: Section "Device" Identifier "Configured Video Device" Driver "intel" EndSection Section "Monitor" Identifier "Configured Monitor" VendorName "Philips" ModelName "190B Flat Screen" HorizSync 30-83 VertRefresh 56-75 DisplaySize 376.3 301.1 Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -H Sync +Vsync EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" "1024x768" "800x600" EndSubSection EndSection I got the modeline from gtf (tried earlier with cvt with same results). Here is some more information. The flickering strips occur only at 1280x1024 resolution. Also, during boot, two error messages appear: error: no suitable mode found error: unknown command 'terminal' ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: xorg 1:7.5+5ubuntu1 ProcVersionSignature: Ubuntu 2.6.32-22.36-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic i686 Architecture: i386 CurrentDmesg: [ 24.828054] eth0: no IPv6 routers present Date: Fri Jun 25 14:25:12 2010 DkmsStatus: Error: [Errno 2] No such file or directory InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release i386 (20100429) Lsusb: Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.32-22-generic root=UUID=33f1eb9d-ac77-4a70-8a39-de7017c7521e ro quiet splash ProcEnviron: PATH=(custom, user) LANG=en_US.utf8 SHELL=/bin/bash SourcePackage: xorg dmi.bios.date: 09/21/2000 dmi.bios.vendor: Intel Corp. dmi.bios.version: EA81510A.86A.0031.P07.0009211842 dmi.board.name: D815EEA dmi.board.vendor: Intel Corporation dmi.board.version: AAA10378-405 dmi.chassis.type: 2 dmi.modalias: dmi:bvnIntelCorp.:bvrEA81510A.86A.0031.P07.0009211842:bd09/21/2000:svn:pn:pvr:rvnIntelCorporation:rnD815EEA:rvrAAA10378-405:cvn:ct2:cvr: glxinfo: Error: [Errno 2] No such file or directory system: distro: Ubuntu codename: lucid architecture: i686 kernel: 2.6.32-22-generic ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 lucid -- video unusable after 10.04 installation https://bugs.launchpad.net/bugs/598481 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg 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
