|
|
Since I have upgraded to modular xorg, I cannot get my dual monitor working on my laptop. Devices register no signal despite XFCE creating two desktops, I guess is the wording (my mouse drags off the edge of my screen whereas otherwise it would not be permitted to).
There have been no changes to my xfce, any settings, or even my xorg.conf. I achieved two desktops by the following in my xorg.conf only (I do not use any programs).
Code: |
Screen "Laptop"
Screen "Desktop" rightOf "Laptop"
|
These options are placed in my ServerLayout section of the configuration file.
Any way I get get my dual head configuration properly working again? |

Sorry the thread-digging, but i have the exact same problem. Since modular xorg went stable I can't seem to set up a working dual-head display.
The two displays are created (:0.0 and :0.1 - I can start apps in both), but the laptop LCD shows only black, the external CRT works flawlessly. I guess the LCD is working, because the backlight seems to be on.
Here's a snippet from my xorg.conf:

OK, I think I kind of solved this one. The only way of getting both screens to work is by plugging the external CRT only after the framebuffer is set on the laptop monitor, otherwise only the CRT screen will show images (the laptop will remain black). Not a neat solution, but at least it works now  _________________ On a long enough timeline, the survival rate for everyone drops to zero |
