Just "upgraded" from 13.04 to 13.10 on my Acer C7 Ubuntu'd Chromebook and first thing I noticed is that everything is very slow and unresponsive. Hardly had this on 13.04. Opened system monitor to check processes and I saw that compiz is consistently using 20-80% of my CPU, even on idle. I tried installing Compizconfig, but it doesn't start up at all.

This is the final release, not a beta. How can I make it more responsive - like it should be?

  • Please remember that you should ask a question. Do you want to ask how you can accelerate everything or how you can install ccsm? Did you install a beta-version or the stable release? Did you recognise such a behaviour in the past? – Nick Lehmann Oct 18 '13 at 12:17
  • Dear mr Lehmann My question is posed in the title and goes "how do I solve the unresponsiveness of Ubuntu in 13.10" Yes, it is a stable release, the official one. Upgraded through the Software Centre. 13.04 ran very well for me. – Roeland Oct 18 '13 at 12:28

Switching the acceleration method from SNA to the old UXA worked for me:

place the following lines in /etc/X11/xorg.conf (create it if it doesn't exist, you will need root privileges to edit the file):

Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "uxa"
#Option "AccelMethod" "sna"
EndSection

  • Weird but true! The new SNA acceleration may score more in games/benchmarks but after switching to UXA the UI became noticeably faster (e.g. rendering tabs in browsers, switching windows, etc.) – Dmitry Pashkevich Dec 16 '13 at 22:00

I had the same problem on my Asus laptop. During the upgrade, the native video driver was removed and not re-installed. Try reinstalling the video driver.

sudo apt-get install xserver-xorg-video-intel

And restart your display manager or reboot.

For me, the upgrade changed my GRUB default menu entry from 3.11.x to 3.5.x, which forced the use of llvmpipe/Gallium software graphics rendering. Editing /etc/default/grub (after getting the right string from grep menuentry /boot/grub/grub.cfg | grep 3.11) and then running sudo update-grub fixed it.

Before figuring this out, I had tried adding ppa:oibaf/graphics-drivers, installing some fglrx, fglrx-pxpress, nvidia-319, nvidia-prime, and xserver-xorg-video-intel packages, and conversely removing the xserver-xorg-video-nouveau and xserver-xorg-video-vmware packages. None of these were improvements; some were notable degradations.
