Screen freezes occasionally, Toshiba Satellite A100, Ubuntu 10.04

Before anyone asks, yes, the system is up to date.

Please tell have you desktop effects active... (if yes try to disactivate them) ?

Have you checked your ram using the memory test function...?

Can you give us the output of this terminal command ?

lspci | grep -i vga

Many thanks, here are the replies:

1. RAM test OK (anything else would have surprised me, because Ubuntu
9.10 runs without problem on the SAME computer)

2. lspci output:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400

3. Desktop effects:
Visual effects is set to "normal". Should I set to "none"?

with kind regards,
Georg

Yes please set to none and try

Hi *,

the problem has just now reoccurred. The "set to none" did not help.

Further help is appreciated.

With thanks, kind regards,
Georg

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

The problem still occurs with the latest updates installed.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

In the mean time, I discovered two things:
1. The screen does not always freeze and become black, it sometimes starts moving (contracting and expanding) weirdly. But it's still possible (wiht a lot of patience) to perform some operations.
2. Once when this problem occurred, I connected a second monitor and enabled it (the screen was moving, not frozen), and the problem disappeared.

Answers are more than welcome, the problem is still not solved!

I have got exactly the same problem as you on the same PC Toshiba satellite A100-165 with ATI Mobility Radeon X1400. I found a very temporary solution by installing in parallel to the radeon driver the fglrx driver from the Ubuntu server and when I restart I have a stabilized display with no crash... but I cannot use the 3D capabilities of my graphic card.
See question 124926 where I am trying to find solution.

For your guide everything runs fine until version 9.10. that is the version Lucid which causes problem. It looks that the radeon driver is nor supporting the X1400 under that version.

For some reason, the question status says "answered", which it is not. How can I get this to the attention of the right person?

I have got the same problem with the same PC, it is not an isolated case!

I am not sure if I understand this correctly. I have already uploaded
the data using the command line below.

Please kindly clarify.

with kind regards,
Georg Profos

Hi,

many thanks for your support.

I just saw that this bug is still in "incomplete" state. Please kindly
provide conclusive information what you need so that it changes to
something active. Or can I do that myself - to what state would I need
to set it, so that fixing may commence?

with kind regards,
Georg Profos

installing the beta version of natty solves the problem
