I installed opensuse 11.2 with a CRT style monitor. I replaced it with an LCD monitor and on startup I see the splash screen, but then then it blanks, and the computer locks up (no response to keyboard or mouse)with a blank (dark) screen - the monitor reports no signal.
If I hook up a CRT monitor it boots OK again.
Intel graphics chip onboard. How do I get opensuse to work with the LCD?
(This is dual boot system - either monitor works fine with windows xp)
Boot into runlevel 3. login as root. Run sax2 to reconfigure your graphics
This is not uncommon when switching from CRT to LCD.
CRTs typically run at 80 or 85 Hz to avoid flickering. LCDs, on the other hand, run nicely at 60 Hz, as flickering is not an issue. Some support higher resolutions, for compatibility sake, but others don’t.
This problem might happen when for some reason X doesn’t have enough info to change the frequency, and keep sending a higher frequency than the monitor supports.
By default X doesn’t create a xorg.conf file anymore in opensuse 11.2, but running sax2 will generate one and, if it exists, X will use it.
You could also try to set your monitor to a lower frequency/resolution with your DE tools (there’s one in KDE control panel, IINM, don’t know about Gnome/others) just to switch monitors, so you can reconfigure it.
Now, if you intend to switch monitors on a regular basis I think you’ll need to use xorg.conf to configure both.
Thanks for the info, that got it working!
