Kubuntu Natty: graphics are terrible when desktops effects (gl) are on

[Edmundo]

Binary package hint: xserver-xorg-video-intel

When I used Maverick, graphics were mostly stable but there was a glitch with screen refreshes... sometimes I had to switch to another desktop and come back so that the screen would be rendered correctly. I supposed that natty would have improved over these problems so I updated today (through apt-get dist-upgrade). Unfortunately the graphics with desktop effects are in a word "terrible". I had to disable desktop effects in order to have a usable desktop. What I'm worried about now is that natty is almost out. If you are hacking heavily on the driver, maybe the problem will disappear with the coming updates, otherwise..... don't want to think of it.

I'm on a samsung N150 Plus netbook.

PS: I just remembered that the natty kernel doesn't want to boot after I dist-upgraded (apparently the root parameter is using the /dev/sda8 format and this kernel doesn't get it). I'll try to see if I can make it boot with uuid stuff and let you know what happens after I start the right kernel.... will let you think about it in the meanwhile.

[Edmundo (eantoranz)]

After starting the right kernel, graphics are much much better.... so maybe this bug is not a real bug after all.

[Edmundo (eantoranz)]

Let me take last comment back. Desktop effects work perfect (so far). he cube, wobbly windows and so on. However, after I start the screen saver (euphoria), the graphics mess up big time.

[Sitsofe Wheeler (sitsofe)]

xorg log says Integrated Graphics Chipset: Intel(R) Pineview GM

[mylh (mylh)]

I also have this problem after upgrade. What do you mean "right kernel"? Isn't it upgraded also?

[Edmundo (eantoranz)]

Yes, it was... but if you check here you'll wee that I had problems in
the update procedure.

http://maratux.blogspot.com/2011/04/my-journey-updating-to-natty.html

The graphic problems remain.

[Edmundo (eantoranz)]

There was an update on the intel drivers recetly so I checked if this is still a problem. I tested Euphoria and it worked correctly (starting and stopping the screensaver). The only detail is that I have a clock on top of it and I had to disable it because when I enabled widgets to be on top of the screensaver, it crashed kwin.

[Travis Shearer (travisshearer)]

The latest update on intel drivers didn't solve the problem for me: I can't even enable desktop effects

[Chris Wilson (ickle)]

Not being able to enable desktop effects is KDE blacklisting them after a previous error. You have to kick it to get it to work again.
