KDE Screen Resolution Won't change
I'm running Slackware 14.0_64 on a HP dv2945SE laptop. The video is GeForce 7150M, the processor AMD Turionx2. I have the latest NVIDIA driver 295.50

The problem is KDE will not change screen resolutions. I have some games that seem to get the resolution to change to 640x480 or 320x200 but when I try to run programs I've written in c++ the screen will not change to capture all of the program screen. It's like the pixel size changes but the picture does. Like Zooming in on a section of the screen. So I though if I try and just change the screen resolution through KDE prior to programming, it might help. Same thing. When I change from 1280x800 to 640x480, the screen just gets bigger and most of the screen has to be panned to see. Then when I reboot the system the screen returns to 1280x800.

I've ran my simple graphic programs from the prompt prior to loading KDE and the programs work fine. However, I like using Eclipse, which in turn requires KDE.

Any suggestions or has anyone else seen this issue before.

Well I wasn't able to get KDE to improve. As a matter of fact, I even used my game background as my wallpaper, and it cut the bottom 1/4 off there too. My bmp is 639 x 470 so it should fit in 640 x 480. Unfortunately 640x480 will not fit on KDE's screen. I'm guessing it has something to do with ratio of width to height for a laptop widescreen vs the ratio of 640 to 480

Either way, for the sake of being able to use Eclipse and programming from KDE desktop, I was able to change my program to use •GFX_AUTODETECT_WINDOWS instead of just GFX_AUTODETECT. This allows me to see the entire 640x480 in a window.(Allegro command)

Hope this helps someone,
