I tried to got to qvga for graphics performance testing about a week ago. This is needed (tested on SHR's 2.6.29-rc3): echo "qvga-normal" > /sys/bus/spi/devices/spi2.0/state xrandr -s 240x320 To return to vga: echo "normal" > /sys/bus/spi/devices/spi2.0/state xrandr -s 480x640 Problems: - SHR's pin entry dialogue and shr-today have a too large font so they're hard to read, but still (kinda) usable, didn't try other apps http://scap.linuxtogo.org/files/3a88e6beb3253362d14384ec3f3a3dfe.png (yes, that's the whole screen) - graphics in general are far too light, most colors become whiteish - colored stripes horizontally over the whole display, but are invisible on screenshots (naturally) - the same as above, but photographed: http://d-a300.selfip.net/files/shr-today-qvga.jpg If our software would run well in that resolution and if the display would make it (better than now), I would clearly prefer qvga for performance. I was about to write a little game, but that's impossible with that horrible vga rendering performance. -- Marcel _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
