Slow perfomance on linux (Ubuntu Dapper)
sque:
Hello again,
For the whole summer I dropped my desktop pc and grabbed my laptop where I have also installed ubuntu with the same almost configuration. I thought that this "bug" was fixed because everything worked perfect on it. Now that I am back, I tried latest C::B on my desktop pc, and I understand that this "bug" appears only on the desktop pc (which is 2 times faster than laptop).
All I am saying is that this is not "an-all-ubuntu" bug, but I cannot understand what's the prob with those individuals pc's.
maybe wrong Xorg conf?
mandrav:
Maybe the graphics card driver? Can you try changing X to use the framebuffer driver on your desktop PC and see if it still crashes?
sque:
1st of all, It's not a crash!
It is just slow, when I type fast the characters appear five-five and not one-by-one. When I move the mouse around inside the text editor I get 100% cpu usage.
I did the following:
* reconfigured xorg to get back the default xorg.conf of ubuntu
Used the "nv" driver and retarted X bla bla...
Results: the same exactly promblem
* Tried to use the "fbdev" driver (You told me something about the framebuffer driver, this you mean?)
Couldn't start x with various of problems that I cannot solve
* restarted X with my usual xorg.conf and DISABLE everyplugin (even compiler)
I opened a c++ file with some code and tried to write...
Results: the same
* (GNOME:) I went at system->preferences->fonts and disabled hinting and smoothing of fonts (really ugly but font rendering is way faster)
Results: C::B was exactly the same slow when typing scrolling etc!
I don't know what's the prob, I am now preparing to build a custom kernel to see if thing changed. On the other hand I am looking around at ubuntu forums as well to find a solution.
(I am here to do whetever tests you want ;) )

Yes, sorry I mixed it with another problem mentioned the same day.
Did you read this post (maybe it helps)?

(If you mean to try profiling..)
Yes I read it... but I cant spent time now for that, I just want to make it work to finish a couple of exercises I have to do for my university. (dipli eksetastiki klp. sry)
(If you mean to upgrade to >libcairo-1.2.2) I must do many tricky thinks to stay at dapper or upgrade at edgy. Both ways sound very unstable for my main pc :S
