I wrote a few days ago to say that the Live CD works OK with my setup. I have now upgraded my installed version from Feisty to Gutsy and have found that the splash screen and boot progress bar does not display because the monitor complains that the settings are out of range. In Feisty the work around for this was to add a vesa code to the boot parameters in GRUB. This no longer works. Does the live CD use special boot parameters for this to work? -- 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 kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

Ah, 64 bit. As I understand it, there are some issues probing monitor info on 64 bit machines that people are working on. Hopefully it will be resolved by Hardy. People not replying probably means they don't know how to help.. that or are jealous of your huge hi-res monitor ;) -- 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 kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[Bug 3731] Re: Xorg resolution falling back to 640x480 and/or 800x600 when h/v freqs incorrect
I doubt the 64-bitness is a problem here, because it got the EDID data
from my monitor. The vesa driver has to use an x86 emulator to run code
from the video BIOS, but I think it manages that fine (Fine here, but
not on my Tecra 8000).
I looked at the source code for ddcprobe (part of xresprobe) and found
the part where it calculates ctimings:
/* Standard timings. */
for(i = 0; i 8; i++) {
double aspect = 1;
unsigned int x, y;
unsigned char xres, vfreq;
xres = edid_info-standard_timing[i].xresolution;
vfreq = edid_info-standard_timing[i].vfreq;
if((xres != vfreq) ||
((xres != 0) (xres != 1)) ||
((vfreq != 0) (vfreq != 1))) {
switch(edid_info-standard_timing[i].aspect) {
case 0: aspect = 1; break; /*undefined*/
case 1: aspect = 0.750; break;
case 2: aspect = 0.800; break;
case 3: aspect = 0.625; break;
}
x = (xres + 31) * 8;
y = x * aspect;
printf(ctiming: [EMAIL PROTECTED], x, y,
(vfreq 0x3f) + 60);
}
}
So that's how it detected 1680x1680 and 1440x1440: It thinks there's
an aspect ratio of 1 because of an undefined condition. Is this the
same code that Ubuntu uses to configure xorg.conf for the vesa driver?
If so, that would explain everything.
By the way, has anyone ever looked at edid-decode? It's awesome. It's in the
xorg git tree here:
http://gitweb.freedesktop.org/?p=xorg/app/edid-decode.git;a=summary
I tried it on my EDID and it correctly parsed EVERYTHING. The output is
attached.
So, I know how people can help with this issue:
Make ddcprobe more like edid-decode. :)

Attached is a patch for the file ddcprobe/ddcprobe.c in xresprobe. Here is the REAL spec for the aspect field of a standard timing descriptor: 00: 16/10 01: 4/3 10: 5/4 11: 16/9 After applying this patch, it mostly works. There's no more 1680x1680 or 1440x1440 when I do sudo dpkg-reconfigure -phigh xserver-xorg. However, I still have to edit xorg.conf and delete 1600x1200 to get X to start. This is an extremely important patch!

Hi My name is Ed [EMAIL PROTECTED] I had a problem installing version 7.0. I could not get a resolution greater than 640 x 480. This prevented me from installing the system, therefore I could not do any of the tweaks that you folks had suggested. My solution was to upgrade my video card and now get a resolution of 1024 x 768. I was able to install the system and am using it at present. Thanks for all the support and hope this info is helpful.

Hi, as this bug seems to be the one where to gather resolution autodetection problems, here I go. Feisty failed to detect well the native resolution (1400x1050) of my laptop screen. That is strange because xresprobe gave the right one. I have no idea what went wrong. It's an asus laptop based on a centrino dothan platform with an X600 graphic card just tested it : xrandr got it right. If you need any debug info, just ask for it.

** 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 ModelNameSDM-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. + Alternatively, you can try running `sudo dpkg-reconfigure xserver-xorg` + and specifying the refresh rates through that interface, if you wish to + avoid hand editing config files. Note that this will replace your + xorg.conf file entirely. + 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 kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
