Xubuntu 6.10 slow

Asked by Jarno Suni on 2007-02-22

I have upgraded from Xubuntu 6.06 to 6.10. I tried hibernate, but had to restart and lost swap. I think I got swap back by some commad I found in ubuntuforums.org, but anyway my laptop seems to be very slow, practically freezes, after some uptime and use. System Load Monitor shows 137MB of 241MB used even if no applications are in run, except that I have added xfce4-mixer, Orange clock, System Load Monitor and Battery Monitor in Panel 1.

I have some odd change in boot sector, as issued in https://answers.launchpad.net/ubuntu/+ticket/3603

Which application is taking up the most memory in System Monitor... Also did hibernate work previously in 6.06?

Jarno Suni (jarnos) said : #2

Well, I am using Xubuntu so I don't know about System Monitor. Xfce4-taskmanager shows that X has VM-Size 375468032 kB, java_vm has 288276480 kB and firefox-bin has 167981056 kB.
If I remember right hibernate did not work in 6.06.

Are you using the composite extensions of Xorg? (shadows, transparency, etc)
In that case, is your system using hardware accel?

I can't try it now, but i think you can check it runing:

glxinfo | grep DRI

The output of the command above is:
libGL warning: 3D driver claims to not support visual 0x5b
OpenGL renderer string: Mesa DRI Intel(R) 915GM 20050225

It turned out that the swap was not in use (after booting at least). Editing /etc/fstab brought swap back after next boot. Now the laptop PC is faster and significantly more usable. I try to avoid hibernate. I wonder why the UUID of swap don't work.

/etc/fstab before editing:

There was also /etc/fstab.pre-uuid (which was /etc/fstab before upgrading to Edgy I suppose.)
