** Summary changed: - Xorg resolution falling back to 640x480 when h/v freqs incorrect + Xorg resolution falling back to 640x480 and/or 800x600 when h/v freqs incorrect
** Description changed: I'm upgrade my system to ubuntu 5.10, after that, xorg can't load the correct resolution of the monitor ( 1024 x 768 ). I'ts only load 640x480. I've used dpkg-recunfigure xserver-xorg, and insert the correct values, but don't work. The system is a Samsung 753dfx and a gforce mx 200 32mb. + + [Update] + A lot of people have reported this same bug. Symptoms include: + + * Your hardware supports a variety of resolutions, but Ubuntu only runs in 640x480, 800x600, and/or 1024x768 + * In the "Monitor" section of /etc/X11/xorg.conf, your monitor is listed as "Generic Monitor", with HorizSync and VertRefresh rates that do not match your monitor + * `xresprobe <driver>` fails to work, or does not return accurate information for your hardware. (You can find your driver by looking in /etc/X11/xorg.conf for the line "Driver ..." It will be something like 'ati', 'nv', 'nvidia', etc. If you are using this on a laptop, run `xresprobe <driver> laptop`. + + The work-around for this bug is to edit /etc/X11/xorg.conf and replace + the rates with ones that match your monitor. The section should look + something like this: + + Section "Monitor" + Identifier "Generic Monitor" + VendorName "SNY" + ModelName "SDM-S91" + Option "DPMS" + HorizSync 28-80 # Important: Use horizontal frequency for your monitor + VertRefresh 48-75 # Important: Use vertical frequency for your monitor + EndSection + + Your monitor's documentation will tell you what the frequencies are. + It's typically on a data sheet in the back of the book titled "Input + Signal" or similar. If you don't have the printed manual, you can + usually also find it on the manufacturer's website. + + The proper fix for this bug is to identify WHY xresprobe isn't working, + and for this we will need everyone's help. Here are some ideas on why + it may or may not work, that need testing: + + * Does it work with DVI monitors? + * Does it work with KVM switches? + * Does it work with DVI-to-VGA adapters? + * Does it work with HD monitors? + * Does it work with multi-headed systems? + * Does it work on non-x86 systems (AMD64, PPC64, et al)? + + If you are having resolution problems, you can help by running xresprobe + (see above) and if it fails, then try to think of anything a-typical + about your system, and report your findings in the comments of this bug. -- Xorg resolution falling back to 640x480 and/or 800x600 when h/v freqs incorrect https://bugs.launchpad.net/bugs/3731 You received this bug notification because you are a member of Kubuntu Team, which is a subscriber of a duplicate bug. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
