configuring the keymap in sax2 breaks the X11-Configuration for the external monitor
Last modified: 2005-11-23 11:50:19 UTC
Dell Latitude C640 in docking station with external TFT 1701FP. In my fresh SuSE 10.0 installation, X11 was working fine, but the keymap was set to american ("us"). I tried to use yast2 to change the keymap into "de" and was asked to test the new configuration. The screen went black and the TFT-Monitor displayed the message "Cannot display video mode". I'll describe the next steps in short: 1) runlevel 3 - sax2 - save default - runlevel 5: everything was fine, but "us" keymap 2) runlevel 3 - sax2 - change keymap - test: "Cannot display video mode" 3) docked out (using panel display): runlevel 3 - sax2 - change keymap - test: everything fine - shutdown - docked in (using ext. TFT) - boot - "Cannot display video mode" 4) runlevel 3 - sax2 - save default - changed keymap in /etc/X11/xorg.conf manually - runlevel 5: everything fine Whenever I changed a configuration using sax2, my external TFT monitor shows only "Cannot display video mode".
Hmm, sounds really weird. In principal changing the keyboard configuration is not the culprit I assume no matter what setting has been changed this problem will occur. Well I need a log to see what happend. If you don't mind follow the workflow below: 1) run "sax2 -r" from runlevel 3 as root from within the docking station 2) do the keymap change... and test 3) the problem should occur now according to your report 4) quit the test --> send me the log file /var/log/SaX.log Additionally you can try to use the current version available here: ftp://ftp.berlios.de/pub/sax/head-build/suse-10.0 Thanks
I followed the workflow as you've described it and the problem occured as expected. After the timeout, the gui of sax2 showed up again and I was able to quit sax2. I'll attach the logfile...
Created attachment 58105 [details] sax2 logfile
The upgrade to the current sax2 version (7.1-28.1) doesn't solve the problem.
I had saved an image of /etc/X11 as it was working and made a diff to it after the configuration was broken by sax2. Would this help? Is there any sensitive information within /etc/X11 I shouldn't make publicly available?
Hmm I'm sorry but I cannot see that ever have configured the secondary VGA of your laptop. I only see a configuration for one display the one currently active.

I'm a bit confused how it was possible to have internal and external VGA working if there is no configuration setup for it :) As you may have noticed there is a small checkbox to enable the dualhead mode if you enable it the problems should fade away
by the way thanks for the very good reporting style. maybe I missundersand something. Could you check out the dualhead setup with the new version you have installed, does it fix your problem ?
... I take all the blame! It *is* working if you activate the dualhead checkbox. However, I didn't expect that I'd need to change the display configuration in sax2 as the default configuration was already working. Thanks for your help!
