After upgrade from Xubuntu 11.10 to 12.04, GUI is slow

[MichiGreat]

Hi!

Yesterday I've upgraded from Xubuntu 11.10 to 12.04 and suddenly the GUI is very slow. For example, switching with Alt+Tab from a terminal to Firefox needs about 1.5 seconds. If I click with the mouse to the taskbar buttons, there is no delay. Restoring a program from minimized state either with the mouse or the keyboard also needs more than a second.

Does anyone have an idea how this could happen and what I could do against it?

Best regards,

Michael

hello my friend
I'm not knowledgeable enough to help you efficiently and I'm not using Xubuntu.

but i think upgrading is the key to the answer.
i think your GUI is slow because you've upgraded.
i know you are worried about your installed softwares you can find them here "/var/cache/apt/archives" make a copy of them and reinstall the Xubuntu.

i am using Ubuntu and i tested Ubuntu both 11.10 and 12.04.
12.04 is really faster and better than 11.10 and this made shocked when i saw your title.
i hope your problem to be solved very soon

Hi!, MichiGreat,


Do you have an nvidia video card, or Optimus with an Intel integrated cpu/gpu??

What you describe sounds like one of the problems from a bug in the 295.40 nvidia driver.

Chao!, bogan.

And today I've installed the fglrx driver and now the GUI is again as fast as a weasel. ;-)
