Switching Screenmode an Freerunner
Hi, I am thinking about porting an emulator for some ancient home computer to openmoko. I don't really need VGA resolution and lots of colours, so I wonder if it is possible to switch the Freerunner to a lower screen resolution and maybe 8-bit palette mode. Does the Glamo support this? Does XGlamo implement it? Does it give a decent performance improvement? I could not find this information in the wiki, so I thought I ask here before digging through the sourcecode of XGlamo. ;-) regards, Andreas Micklei ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Switching Screenmode an Freerunner
xrandr -q and xrandr -s 240x320 work for me (and effectively crash X, since you can't use the keyboard any more, and illume doesn't adjust very well... Also, the touch screen doesn't seem to understand that the resolution change, which makes using it pretty difficult. Finally, display looks kind of funky in 240x320 mode, almost as though it's not quite driving the LCD correctly. I have no idea how to get it into 8 bit mode. -Rusty Andreas Micklei wrote: Hi, I am thinking about porting an emulator for some ancient home computer to openmoko.

Looks like the foundation is there, so I will try the xrandr commands and see if I can find out a little more. For the LCD mode: Does anybody know if this is supposed to work correctly and just needs fixing with a better modeline or something, or is this is a hardware limitation which can't be fixed in software? I have no idea how to get it into 8 bit mode. Would be a plus, but maybe 240x320 is already fast enough. regards, Andreas Micklei ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
