MX is slow after lqast update

[jerry525]

boot into init 3 and run sgfxi as root
you might have to do this twice

Sorry I am not very technical, can someone explain how to do this please.

[Stevo]

Don't bother with sgfxi, it's good for detecting and making sure the system is using the driver for Intel graphics, but you're already using the Intel driver. We can check what driver is installed with

Code: Select all

apt-cache policy xserver-xorg-video-intel

If it's the backports version, we can try going back to the standard Wheezy version and see if that fixes it.

Ok thanks for that.

Code: Select all

$ apt-cache policy xserver-xorg-video-intel
xserver-xorg-video-intel:
  Installed: 2:2.21.15-2~bpo70+1
  Candidate: 2:2.21.15-2~bpo70+1
  Version table:
 *** 2:2.21.15-2~bpo70+1 0

     2:2.19.0-6 0

Do I just unselect the backports repo ijn synaptic then update?

The following should downgrade it. It's a simulation. If the simulation looks okay remove the "-s" and run it again for real. {post the output of the simulation if you're unsure}

Code: Select all

su -c 'apt-get install xserver-xorg-video-intel/wheezy -s'

After downgrading it you'll need to pin it so it doesn't upgraded again. You can do that in Synaptic, or you can use the apt-mark hold cli command :

Code: Select all

su -c 'apt-mark hold xserver-xorg-video-intel'

edit: after doing the downgrade you'll also need to restart X or do a shutdown/restart to see if the downgrade fixed the slowdown problem.

[jerry525]

Yes pls check the simulation output for me:

Code: Select all

$ su -c 'apt-get install xserver-xorg-video-intel/wheezy -s'

[kmathern]

It's correct. (it will downgrade the xserver-xorg-video-intel package to the 2:2.19.0-6 version)

[jerry525]

Worked an absolute treat!

I'm so pleased & relieved.

Many thanks for your and everyone else's help.

Thank you all for this fix for a problem I didn't realize I had.

Hadn't been on the desktop much over the last few weeks.
Just thought it was slower than it used to be; however,
it was still faster than the netbooks so I just adapted.

[Stevo]

That's too bad about the new driver messing things up. What Intel chipsets has it affected badly so far? And is there anyone using it successfully?

Also, what exactly do you mean when you say the system has slowed down? Are screen redraws slow, and does "top" in the terminal show xorg eating all your CPU cycles?

My Acer One D-250 (Atom single-core with HT, 2 GB RAM) hasn't had a problem that I'm aware of. However I'd have to check to see if this upgrade was made on it as I don't upgrade it very often. Last time was on 9/13.
Is it possible that something connected to the Intel driver wasn't configured correctly (or even upgraded)?
