[Bug 1078161] [NEW] Ubuntu 12.04 LTS very slow (unusable) after resume from suspend

 

Public bug reported:

This is similar to Bug #1004475 which is marked incomplete and so creating a new one. 
I am new to ubuntu. installed 12.04 LTS on old Toshiba satellite a10-s129 laptop. It has intel graphics. Overall I really liked the experience but I am experiencing the same problem when laptop resumes from suspend. The desktop is unusable. I have to power off and power on to reset. It has the following intel integrated graphics : (lspci output)

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 01)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 01)

I didnt see any process taking a lot of CPU. I did see Xorg and compiz
taking up about 4-5% (seen thru top). I have 512M RAM on this.

Description:	Ubuntu 12.04.1 LTS
Release:	12.04

I can provide any additional information required to troubleshoot this,
if required.
