Bug Description

Since upgrading to Hardy 8.04 I've been getting intermittent 'out of range 17.3 / 16hz' errors on my LG Flatron L1915S. I can boot into X fine, but every so often the monitor will show this error, then I have to crash out of X (ctrl-tab-backspace) and login again. This happens several times per day.

I've done a fair bit of searching, and while there's a few superficially similar reports and a general complaint about dpkg-reconfigure xserver-xorg not allowing for manual configuration, I'm hoping this isn't a duplicate, apologies if it is.

Video card is a Radeon 9200 pro, using the open source "ATI" driver. In Gutsy I had to set AGPMode "4", this hasn't changed in Hardy - otherwise it was working fine before upgrade.

I've attached my xorg.conf - this one generated by displayconfig-gtk. I have the same issue with the auto-generated hardy version, and my old gutsy one (would attach those too but there's only one upload field).

I'd be happy to provide any more information to help sort it out. I'm only up to copying and pasting configurations and running cli scripts - don't know enough to debug the actual issue myself.

Thanks for any help.

Nat

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at [WWW] https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in xserver-xorg-driver-ati.

Please attach your X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

Also, please include the information requested at [WWW] https://help.ubuntu.com/community/DebuggingXAutoconfiguration as separate attachments.

Thank you.

I wasn't sure whether to put it as an autoconfiguration bug or the driver, thanks for doing so.

I've attached the last two Xorg.log and the debugging information as separate attachments. I should note that running with no xorg.conf (or the one generated from dpkg-reconfigure xserver-xorg) gives me the AGP 8x/4x 'fuzzy screen' bug mentioned earlier (there's an existing issue for that with advice to set to 4x) - hopefully there's enough from the login screen and a few ctrl-alt-backspace for it to show up in the log though.

Thank you for following through with this. I am changing the package from xserver-xorg-driver-ati to xorg because of the autodetect problem. It seems strange that it only goes out of range some of the time - I originally classified the bug under the driver because of this, but it does seem to be a problem with xorg not working with your monitor correctly after all.

I will mark this bug as Triaged with High priority so a developer can start working on it. Please post one last thing to the bug report, the output of
  apt-cache policy xorg

Thanks again. Attached that too.

FYI, the correct driver source package would be xserver-xorg-video-ati (the xserver-xorg-driver-ati package is obsolete). The mode detection should work "automagically" with no (or a minimal) xorg.conf.

Please use the device option "ModeDebug", and attach the corresponding log.

Worth adding there's an existing issue open for Radeon 9200/ATI/AGP breakage over at https://bugs.launchpad.net/xorg-server/+bug/139210. afaik it's a completely separate issue to this "out of range" error - I've just subscribed over there and updated the issue.

Although it's intermittent, it <em>seems</em> to occur only when there's some kind of graphical activity happening (i.e. opening a newpage in a tab in firefox - although frankly I pretty much live in vim and firefox). Should also have noted I'm using compiz - although had no previous issues with these in gutsy and the settings are the same.

I won't be at my home pc again until this evening, but will supply a log with ModeDebug enabled then. Thanks for the quick responses so far.

Here's the xorg.conf with ModeDebug enabled.

Just had the out of range error with ModeDebug still on, so here's a log from just now. Not sure if it's any help but can't hurt.

Please use an autogenerated (minimal) xorg.conf with just the ModeDebug and AGPMode options added, and reattach new log files and xrandr output.

Ok back to a minimal xorg.conf, here's the xrandr output and log.

And does the now default mode of 1280x1024 @60.0 cause the "out of range" issues?

Did it pick the same mode in Gutsy? Maybe you can provide an old log from Gutsy or run a Gutsy live CD?

Do you have something plugged into both the VGA and DVI port?

Hi Tormod,

Not been enough time yet to see if I get the 'out of range' error with this specific config - it's usually once or twice a day so post back if/when I get one.

I'll look to see if there's a gutsy log around. I have a monitor plugged into the DVI port, but it's not configured or set up, apologies for not thinking of that earlier :(

catch (catch56) wrote :

OK. Just got the same error with the minimal xorg.conf. I've now unplugged the DVI cable so will see how it goes like that.

catch (catch56) wrote :

So far so good without the DVI cable plugged in. It's another LG monitor, 22" and can handle different resolutions - like I said it's actually been used in either gutsy or hardy yet - although it's been plugged in for ages and made no difference in gutsy.

Thanks for taking the time to report this bug and helping to make Ubuntu better. In the development cycle for Intrepid there have been some vast improvements in the open source ati video driver and we could use your help testing them. Could you please download the latest Alpha CD image of Intrepid and test this particular bug just using the Live CD? You can find the latest image at http://www.ubuntu.com/testing . Your testing can help make Ubuntu and the open source ati driver even better! Thanks in advance.

My 24 inch monitor has a native 1920x1200 resolution. I have this bug on that monitor. My workaround is working on 1680x1050, but that just looks ugly. Working on a radeon x1550.

Sorry, forgot the log. I tried working without xorg.conf, but it doesn't make any difference
