Today I found that an update to the Jaunty packages changed something subtle and the previously working xorg.conf settings were no longer effective. The symptom was the intel driver deciding it is possible to do 1360x768 on the 1024x768 monitor.
The intel driver also ignores monitor options "PreferredMode" "MaxClock" which meant the pixel clock rate of the monitor can't be specified, to prevent the incorrect mode. I used the Windows tool, PowerStrip, (referenced from the Xorg FAQ at http://www.x.org/wiki/FAQVideoModes#head- 82230a582646cbf28ac41dec2139732ee868e0d2). to get the ModeLine that works for Windows. That didn't help either because the intel driver either ignores it or merges it with its own calculations. The final solution was to add the "Virtual" size setting to "Display" SubSections of the "Screen" section. Here's the resulting xorg.conf: Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Sony Notebook Panel" # no EDID DisplaySize 210 158 HorizSync 28-48.5 VertRefresh 43-75 Option "DPMS" # clock is in kHz Option "MinClock" "10000" Option "MaxClock" "65000" Option "PreferredMode" "1024x768" ModeLine "1024x768" 65.000 1024 1048 1184 1344 768 771 777 806 -hsync -vsync EndSection Section "Screen" Identifier "Default Screen" Monitor "Sony Notebook Panel" Device "Configured Video Device" DefaultDepth 24 SubSection "Display" Depth 24 Virtual 1024 768 EndSubSection SubSection "Display" Depth 16 Virtual 1024 768 EndSubSection EndSection -- [i815] Wrong resolution on Vaio PCG-SRX51, PCG-SRX41 and PCG-FX370 due to incorrect h/v rates https://bugs.launchpad.net/bugs/288807 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
