Strange GTK(2?) apps slowdown after unsuspend

Zviratko

Hi,
I have a Centrino laptop (Dell Precision M60), and I use suspend-to-ram regularly (twice a day). Recently (say, last week or two) when I resume the laptop and use some GTK2 apps (mozilla suite, firefox, ethereal, xmms) they are slow and laggy - like if my processor was slowed down (but it isn't, I made sure). Reboot fixes it.

I use KDE desktop, all QT-based apps work fine, mplayer works fine (no slowdowns, I can see the CPU usage difference when switching frequencies).

my CFLAGS (I use gcc-3.4):
CFLAGS="-mtune=pentium-m -march=pentium-m -O2 -pipe -ftracer -fweb -momit-leaf-frame-pointer -funit-at-a-time"

I use ac-series kernels (2.6.11ac1 currently), ck-series had the same behaviour.
I have not changed my kernel config or CFLAGS, I did however upgrade to kde-3.4.0-rc1 recently (not sure if it happened with beta2).

Anybody experienced this?

has you may know Gtk belongs to Gnome and once you using gnome apps on kde it may increase your cpu and ram usage , try qt-gtk its a great tool for those kind a things

same answer, or you can check your kernel configuration, maybe on acpi

When you say "as if your cpu is slowed down", do you mean like speed stepping? If so, is it speeding down?

XMMS is gtk1 by the way, but I don't think that helps. I don't really have much of a solution for you, except to keep an eye on top and see if any weird processes are running after the suspend.

you cuold check if you have something like xscreensaver or something like that or something that starts running on the background and slows down your machine do a

I have exaktly the same problem, since gtk+ 2.6.7 got merged (I think). After a while all gtk apps are unusable slow, while QT apps are working fine. when I enter this text in firefox, the CPU usage reaches 100%, in the moment I give the focus to a qt app. the CPU usage is normal (20%).

i think it is a problem with gtk+ 2.6.7

PS: I compiled firefox with USE="-gtk gtk2", maybe you compiled mozilla using gtk1

Simple ! Run an app that uses gtk2 and see if it increases your cpu , if it does then recompile that same app against gtk1 and lunch it again and see what happens !
gtk2 latest working fine here !
