Default Monitor refresh issue

Dear all,

I have a laptop DELL inspiron 1525 that worked fine ever since 8.04 up to
10.04. I did on it a fresh install of 10.10 and after that the monitor started
to freeze every 10-20 seconds. This can be seen while pressing page down on a
webpage, or typing an email, or scrolling through windows, or by dropping a
menu down -- all that makes it move... As a visual effect it looks like the
monitor cannot refresh itself correctly.

This is happening with composing on and off, so it is not that. The monitor
settings are the same as before.

Any ideas?

I had a similar problem on my inspiron 1525. It vanished completely after I
set the desktop effects to use XRender instead of OpenGL.

Yes, it helped but also disabled all of the effects I like, so I had to switch
OpenGL back again. Any other option?

Not a fan at all of "fresh install" types of upgrading as you do lose your
working setup. One of our people had a problem much like that when he tried
the windoze way and did a fresh install of 10.04. We never found out what
caused it so reinstalled the 1525n 8.04 backup we have and then upgraded that
directly to 10.04. Net result is that everything now works perfectly and he
has sworn to NEVER fresh install again!! Windoze habits are hard to break!

OTOH I once did an upgrade from one release of kubuntu to the next and ended
up with a totally inoperable system.

Thus, I have *always* done fresh installs ever since.

To each his own.

After my upgrade from 10.04 -> 10.10, the OpenGL option was disabled.
Something about the driver being blacklisted.
I guess it's either XRender or the artefacts - your decision. (Or get a proper
3D graphics card... :-P)

"Proper" upgrades will ultimately always leave some config files or outdated
config in place and neglect to activate new features. For me, something caused
my X server to crash every now and the when I pressed enter and some other
keys. That bug wasn't present after a re-install, so that really was the only
long-term option available.

Also, not every distro behaves as well as Debian-type ones when upgrading.
Back when I was still using Suse, one simply had to re-install every couple
of releases because the system became unusable due to an extreme amount of
garbage.

A nice, fresh start with a fresh, clean install often is the only sensible
option.

Plus, if you keep good notes from the last release, it is not a major problem.
And as you mentioned, you find out about new features.

And, going over the old config files is always a good refresher....

And,,,,, if something appears broken, you know it is probably a new bug
rather than some incompatibility with the upgrade.

And...........
