Using extended desktop, application disapears from taskbar.

[Brian Vilhelmsen]

Binary package hint: xorg

When using extended desktop the application disapears in the taskbar when dragging the application to the extended monitor. The only way to access it is to hit alt-tab.

Expected:
Application should stay in taskbar.

Laptop model: HP Pavilion dv5
Extended Monitor: 19 inch JW199A HANNS-G

Not sure which graphics driver is in use. I have the nVidia accelerated graphics, but it is not activated.

sounds more like an application bug than driver.

I noticed that this kept happening when I was moving my laptop back and forth between work and home. At home, i don't use extented desktop, but I do at work. I guess when I boot the machine at home it saves some settings, and when I return to work and connect my extended monitor, the applications are visible in the taskbar only when the application window is placed in the 'primary' monitor.

To fix the problem, I log out and then back in again, while the extra monitor is connected. A bit anoying.

Hope this helps.

could you try on jaunty? there is monitor change issues which have been fixed recently

[Sebastien Bacher (seb128)]

closing there is no recent comment and the issue might be fixed in jaunty, you can reopen if that's not the case for you

The problem was not fixed in 9.04. I am running the latest update. I have an extended desktop with the extension on top of my primary (laptop) screen. I have a taskbar at the bottom of the pair which shows icons of windows. Windows only show up on the taskbar if they are more than 50% in the bottom part (screen) of my extended display.

I just ran into the same problem after adding a displaylink device (EVGA UV+).

Previous configuration:
9.04
Ati card with 2 monitors running an extended desktop. Moving a window to the right monitor did not make it disappear from the taskbar on the left monitor.

setup: xrandr --output CRT1 --auto --right-of DFP1

Now i tried adding a 3rd independent screen using the USB converter, and while everything else works fine i suddenly have the same problem: moving a window from the left to the right monitor makes it disappear in the taskbar.
