I have very strange problem. After upgrading to Kubuntu 9.04 from Kubuntu 8.10 the whole system works veeeery slow. I thought that something went wrong during upgrade process, so I have formated disk and installed 9.04 from scratch. Unfortunately nothing changed... System boots up, KDE is loading. First impression seams to be OK. But problems come when I try to use some GUI apps. Dolphin, Krusader, System Monitor - whatever - the same effect. If app is in small window it works more less OK (closer to less :P, slower then on 8.10). Total failure is when I put app into full screen - KDE freezes, sometimes for good. Even terminal window works the same if I maximize it to full screen. I have done some measuring with system monitor, and it seams that Xorg process is swallowing all processor power if I do something as I describe. When I do some things from console system is responding properly, so my guess is that something is broken with KDE?

Re: KDE works very slow after upgrade to Kubuntu 9.04
I would say that kde 9.04 is some way ahead of its predecessor.
Once you have started up open a terminal and type top. This will monitor all the running processes. Is there anything that seems to be consuming excessive resources? -
Re: KDE works very slow after upgrade to Kubuntu 9.04
Just as I said - Xorg consumes almost all CPU power during launching any application. If bigger the window, then Xorg consumes more CPU. It's fully replicable. I launch terminal in small window, type "top", Xorg consumes more les 5-10 %. But if I hit the full screen, Xorg consumes ~95%. I think, that my problem is similar to the one posted after me here:
http://kubuntuforums.net/forums/inde...opic=3103329.0
but I'm a little step further because I know what is cosing this but don't know why, and how to fix it... :/
EDIT:
When I return from full screen terminal, to default windowed (much smaller) one, Xorg again consumes ~5% CPU power.

Re: KDE works very slow after upgrade to Kubuntu 9.04
What graphics card have you got?
Also, have you got desktop effects enabled (system settings/desktop?)Comment

I have always problems with this card. I have tried few linux distributions and there were always problems with 3D and advanced desktop effects - but never such like this. Without advanced desktop effects any system earlier worked fine.
They are disable.Originally posted by The Liquidator
EDIT:
I have turned off font antialiasing and system works slightly better, but still... it's unacceptable...

How old is the machine and card?Comment

Re: KDE works very slow after upgrade to Kubuntu 9.04
It's about from 2001. The machine is a laptop Maxdata Pro 660X. It's old machine, I know, but it's power is enough to surf the Internet, writing docs, etc. It worked fine on Kubuntu 8.10. I don't see here (on 9.04) any GUI improvement that may cause so slow work of entire KDE. On Windows XP it's also working very well, so this shouldn't be a case of an old, crappy hardware. Graphic card has it's own 32 MB RAM. It's more then enough to display 2d graphic in 1400x1050 resolution (native resolution of laptop's LCD display).

Re: KDE works very slow after upgrade to Kubuntu 9.04
I have as a spare machine an old PB EasyoneDC from the same era (Duron 700, ATI Mobility card) that frankly is inadequate to cope with the demands of KDE 4. I suspect yours is of the same era.
I have found it to work a lot better (i.e quicker) with gnome or xfce as the desktop. Can I suggest you install the ubuntu-desktop and the xubuntu - desktop packages to see which one floats your boat. Either of those , I would suggest. would run quicker for you than kde. Try the gnome desktop first as a half-way house. The beauty of linux is, of course, that you can try them all

Re: KDE works very slow after upgrade to Kubuntu 9.04
Ehm :> Maybe the same era but not the same speedI have as a spare machine an old PB EasyoneDC from the same era (Duron 700, ATI Mobility card) that frankly is inadequate to cope with the demands of KDE 4. I suspect yours is of the same era. You can't equal Duron 700 and Pentium III Mobile 1,2 Ghz with 512 kB cache on board. This Radeon has also enough power. Hardware is not the case. On kubuntu 8.10 with the same KDE 4.2 everything was working smoothly. Something is broken in Kubuntu 9.04.
Yes I may do that, but... I want KDE!! :P Gnome sucks because you can't configure vertical taskbar there... Yes it's essential to meI have found it to work a lot better (i.e quicker) with gnome or xfce as the desktop. Can I suggest you install the ubuntu-desktop and the xubuntu - desktop packages to see which one floats your boat. Either of those , I would suggest. would run quicker for you than kde. Try the gnome desktop first as a half-way house. The beauty of linux is, of course, that you can try them all Smiley I don't understand why gnome developers ignore such thing... Specially in the era of wide screen monitors, especially those 16:9 #&%$ty crap that steals our work space :/

Re: KDE works very slow after upgrade to Kubuntu 9.04
Point taken
I don't know whether there are proprietary drivers available for the card but if there are have they been installed?

Re: KDE works very slow after upgrade to Kubuntu 9.04
This is default driver from kubuntu but it seems to be OK.
Command:
glxinfo | grep direct
returns "Yes" so in theory I have even acceleration
Nobody hasn't got any idea what to do with this crap?

Re: KDE works very slow after upgrade to Kubuntu 9.04
I have found perfect "solution" for this problem... I have installed KDE 3.5, and everything works smooth, even better then on kde 4.2 Oh.. almost everything :P Some applications like firefox, open office or krusader don't start, but I think it can be repaired somehow....
