Unfortunately, when booted into KDE4 now nothing has changed. KDM and KDE4 are still in 1024x768 resolution with Xorg being in 1280x800. The K desktop environment for some reason has always seemed to not use Xorg like the other desktop environments such as Gnome. For this reason I am not sure if this is a KDE bug or if the DE can't interface with the GFX driver properly because the GM45 chipset is not supported and defaulting back to the old i915 derivative as shown by running dmesg. There are two more things we can try; the first being to upgrade the Intel chipset, xserverxorgvideointel, driver to the latest version. If running an Ubuntu based system like we are doing right now, we can go to this location: https://launchpad.net/~ubuntuxswat/+archive/xupdates and follow the instructions on the site.
Just for duplication purposes:
Run nano /etc/apt/sources.list and add the following lines to the end of the file:
deb
Table9. Apt souces.list file entry.
After that we need to add the additional shared key which without running: aptget update will come up with missing key errors.
Running: aptkey adv keyserver keyserver.ubuntu.com recvkeys 123456789
where 123456789 is the key from the SigningKey part of the xupdates page. For the current key, AF1CDFA9 should be added in place of 123456789. Then run: aptget update and finally: aptget upgrade to get the newest Intel video drivers.
Once this is done, reboot and boot into the recovery mode for the kernel in use (should be the latest!). Now follow the menu to root user of who's description should say: Drop to root shell prompt
From there run: dpkgreconfigure xserverxorg, and follow all the prompts leaving all values at default apart from the keyboard type which you need to put in the 2 letter country description. Then let's bring the system up to runlevel 5 by issuing the init 5 command. Unfortunately we have the same problem with KDM being in 1024x768 resolution and KDE4 being in a weird 1024x768 on top of 1280x800. This can be checked when running Konsole as the default size for 1280x800 should be 81x36 which allows two terminal windows to run side by side, however if the window sizes are 1024x768 then one Konsole window will take up more or less the whole screen. When running a widesceen movie though say like the CSI Miami example given earlier, the movie sits perfectly on the display and the size is as should be.
Of course this is very odd behavior and means that something is not right! I will contact the KDE developers about this issue soon and see what they say and according to their thoughts on the matter contact the Intel Linux driver development team and explain the situation and see if there is a fix for it. The output of this can be seen below:
