Ubuntu 12.10 multi-monitor support is having issues
I just installed 12.10 beta 2, and updated all the packages. I was hoping that multi-monitor support will get better, but I was in for a big surprise: not that it isn't better, it's worse than it was in 12.04.
I have a i5 machine with 8GB ram, AMD 7950 graphic card, an Dell 24" monitor and Acer projector. After the installation on HD (I used open source driver), my system was configured in mirror mode, with 1024x768 resolution (Screen01; 1400x1050 was just chosen, not applied, it was changed to 1024x768 before turning off mirror mode). In 12.04, because I was unable to mirror monitor's 1920x1200 to projector's 1024x768, I was keeping them in side-by-side configuration. So, my first impulse was to turn off the mirror mode (Screen02, screenshot of Expo view on Screen03). After clicking on Apply, I got all my windows dissapeared (Screen04, photograph). As it turned out, all my windows were moved to second screen (projector, which was just plugged in, but not turned on), which can be seen on screenshot Screen05. Expo view also gave me nothing (Screen06, photograph), but screenshot of Expo view shows that there are windows (Screen07) - why is this different???
On my next attempt, I turned off Mirror mode AND turned off the projector at the same time, and was finally able to see all windows on the monitor. After that, I changed monitor's resolution to 1920x1200 and I tried to turn mirror mode on, and got completly screwed-up desktop (Screen07). I tried to expand shrinked windows and got something like Screen08. Because it was impossible to recover desktop, I logged out and logged back in, and launcher was gone (Screen10). After several failed attempts to bring it back, I logged out, deleted all settings from home folder (.config, .compiz, .gconf), logged back in and launcher was back.
Additionally, on Display settings, if I click on projector icon (Acer), and then on monitor icon (Dell), I cannot click again on Projector - it just isn't active anymore. By accident, I discovered that area ABOVE the projector icon was active (Screen11, there is no cursor on screenshot, but you can see the tooltip just above from where it is).
My next test was to see if windows are on their places when projector display is turned on and off. Screen12 shows initial window configuration, with projector turned off. After turning projector on (Display settings), the windows were moved, just like in 12.04 (Screen13). Additionally, terminal and text editor were maximized (they weren't before). I then aranged windows to where they should be (Screen14), turned projector off, and they were moved again (Screen15). Notice that terminal and text editor windows are split between two workspaces, but one half of text editor window isn't visible. After clicking on it, the other half became visible (Screen16).
Additionally, whenever I turn projector on or off, the mouse is moved on some seemingly random location.
There is more, but this is what I experienced in the first half hour of trying 12.10 beta 2. All pictures are in attached archive.
If someone needs me to do additional tests, I'll gladly do, because 12.10 in this state just isn't usable for me.
