Screenshot of the bad behavior
The screenshot shows that the two screens are merged into one. The first screen
is set up for 1024x768, the second is 640x480. The second should be displayed
on the TV, not on top of the first.
This has worked mostly on KDE3, except the background image.
(Just a short notice: the background problem of KDE3 is #132307) I experimented a bit more, and seems to be a general KDE4 problem. I tried: >export DISPLAY=localhost:0.1 >konsole & konsole came up on the second head, kwin managed its window correctly. now I tried: >export DISPLAY=localhost:0.0 >konsole & konsole came up again on the second head! So it seems that one app can only be displayed on one screen at one time. Pure X apps (like xterm), Qt4 apps (assistant) are OK. Seems it's a problem with KUniqeApplication...all apps which inherit from this class, not from KApplication suffers from the problem. I investigated further...all apps, which creates new windows in newInstance() inherited from KUniqueApplication, should respect DISPLAY somehow. Its not clear for me that this is the problem with plasma, but plasma is a KUniqeApplication. But now, the "product" assignment is wrong, since it's clearly not a kwin problem. |
