When I swith to external monitor It works for a few time and the screen goes to a solid color. I don't get it works until i reboot the machine. The Fn+F5 switcher is not working - as described in release notes of Intrepid 8.10 - so I can switch to LCD without a reboot. Ctrl+backspace don resolv.

This problems occurs only after I update to Intrepid 8.10

My notebook is a toshiba satelitte U205 S5034 and VGA is Intel Corporation Mobile 945GM/GMS.

I have the same problem. I have a toshiba A100 with Intel945 chipset. When I connect the external monitor, it works fine,
but after some random time, it turns to black or sometimes other colors and I can not make it work again unless I completely restart the computer (even restarting the X does not help). I have also noticed time to time jitters on the monitor picture, it is like for a moment the video signal goes on and off.

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I just installed Xubuntu 9.04 (Jaunty Jackalope) with x.org 1.6 on my Dell Latitude D420 laptop with Intel 945GM/GMS graphics. I experience the exact same problems. I will get back to you later today with some details!
