Keyboard, mouse and screen very slow since upgrading to Lucid

Asked by John Wilson

Keyboard, mouse and screen all are very slow since upgrading from Karmic to Lucid using Update Manager.
Reverted to a wired keyboard and mouse which seemed to help temporarily.
With updates this problem seems to be getting worse so that my computer is almost useless for word processing as I have to wait for the screen to catch up

can you give the output of:

sudo lshw -C display

Thanks.

Is the system a laptop or desktop? Does it have a brand / model?

Thank you for your reply.
I am having problems with my desktop which is about 5 years old. In Windows it runs on XP
Here is the output of sudo lshw -C display:

You may want to hash up an xorg.conf file to make it better, and/or log a bug with xserver-xorg-video-radeon. If you boot to recovery root console and remove the package using apt-get and reboot, you can then boot to failsafe vga and reinstall the package which may make things nice after a reboot.

Thank you for your prompt reply and suggestion.
I was pretty happy with the performance until the upgrade.
The screen speed makes watching u-tube frustrating. It is more the screen response to the mouse and keyboard that I find so disabling.
Where do I find the xorg.conf file?
Once found how do I hash it up?

You will need:

gksudo gedit /etc/X11/xorg.conf

The X is CAPITALIZED. The file will be blank most likely but if you hunt around online you will find sample files which you can experiment with. If the system is a laptop, you may find files which make it work well.

You will need:

gksudo gedit /etc/X11/xorg.conf

The X is CAPITALIZED, the file will most likely be blank. You can find guides online if you search for the video chip named in your lshw output above. If the system is a laptop then you could search for the make / model of the device to find guides for Linux, people like posting how they got the systems nice online to help others.

Thank you once again but this is a bit daunting..
The meat of my /etc/X11/xorg.conf file is:
Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 SubSection "Display"
  Virtual 1360 768
 EndSubSection
EndSection

Section "Device"
 Identifier "Configured Video Device"
EndSection

From a website Hardware4Linux I learn that:
Manufacturer: ASUSTec Computer (by ATI Technologies)
Model: RV 380 Ox3e50 [Radeon X600}
Bus: pci
Type: VGA compatible controller
Id: 1002
Info 2: 3e50
Info 3: 1043
Info 4: 0020

Can you suggest how I alter the /etc/X11/xorg.conf file?

Change

Section "Device"
 Identifier "Configured Video Device"
EndSection

To:

Section "Device"
 Identifier "Configured Video Device"
 Driver "radeon"
EndSection

Save the new file and reboot, may help
