1 sec delay - Minimized window to foreground

English Applications
1

Hi,

I’m Linux beginner at all and I’ve installed OpenSUSE with GNOME a few days ago.

I have found that if I minimize window and then I want to transfer it to foreground, it takes about 1 second delay, what is rally too much for me. If window is not minimized, only behind some other windows, there is no delay.

Could you please suggest me how to fix this delay?

Thanks very much!

Happy New Year and welcome to the forum.

Your info is a bit on the low hand. Is this about "un-minimalizing the window hidden in the task manager?

What is the video-card used? Is 3D support enabled?
Which openSUSE ?
32/64 bit?

This is my PC: MS-6585, Pentium4 2.8GHz, 1GB RAM, HD 2600XT AGP 256MB
so I have 32bit. My OpenSUSE is 11.2

I’ve installed ATI Drivers following “Easy way” described here ATI - openSUSE and “glxgears” runs fine, so I guess that 3D acceleration is enabled.
EDIT: okey, glxgears doesn’t run fine, in resolution 1024x768 I’ve got this output

...
82 frames in 5.1 seconds = 16.201 FPS
83 frames in 5.0 seconds = 16.597 FPS
95 frames in 5.0 seconds = 18.886 FPS
89 frames in 5.0 seconds = 17.780 FPS
...

How can I test if 3D support is really enabled?

Yes, and delay appears when un-minimizing window hidden in task bar.

glxinfo | grep direct

This should result in something like this:
direct rendering: Yes
GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access,

The first line should be the same, the rest might differ.

Mind, you’re using an old AGP card. Don’t expect the driver(s) to improve performance to a level the card simply does not have.

You might find solutions in turning off some of the desktop effects.

Run LiveCD with KDE. Don’t install the OS, but install the driver the same way. See whether the delay improves.

I have got only 1 line

trebi@linux-398t:~> glxinfo | grep direct
direct rendering: Yes

okey I’ll try KDE LiveCD

@Zstefan: could you explain your post. I don’t get it at all, and doubt that the OP will.

What’s it like if you disable the desktop effects?

9

great, disabling desktop effects helps for windows :-), now they appear immediately, but there is still problem with “Computer button” (in left side of task bar), the menu will appear still after 1 sec after click on it

The issue does not seem to be in driver, rather than in window manager.

So trying KDE will open a possibility for hardware to work normally.

Trying from Live CD will bypass the need to install the OS just for testing.

Later, if successful, a full KDE install can be performed.
