I own a pc Pentium III 933 MHz (RAM 256 Mb) supported by an “Elsa Gladiac 511” grafic card (an old one), with a “NVidia GeForce 2 DDR” chip (RAM 64 Mb).
This is surely an obsolete system but it worked very well with “QiLinux 2”.
I tryed to update to “OpenMamba” but I encoutered some problems with the grafic card.
At first, the display started at 640×480 mode without any chance of switching to a better resolution at all (Whereas QiLinux allowed to select the screen resolutions during the installation procedure).
Furthermore, I noticed a very very slow performance in OpenGL applications (like screensavers) I didn’t encounter previously.
