I didn't want to recompile and modify the source, so I used a dirty trick. I just

oh my. I've been one of (if not THE) first who noticed that nasty bug that prevented me using xdirectfb.

Nice job sorting that out. I think I'll give xdirectfb another test drive with this in mind.

Thanks

Added:

I'm in xdirectfb now. As I checked for the devices, I got hesitant. I'm using pure udev, so in theory, i should have only the devices that have been asked for. Since both /dev/psaux (symlinked to misc/psaux) and /dev/input/mice are there, I got scared of breaking something.

Basically, I'm asking, is there one better than the other to delete. I know it sound stupid, but I keep wondering why both are there (could be only gpm for /dev/psaux).

afaik, /dev/psaux is for ps/2 mouse and /dev/input/mice is for usb mouse. Since I'm using a usb mouse, I just delete the ps/2 one. (although connected through a ps/2 port. I'm using a KVM switch to connect 2 boxes to one monitor. That saves me a lot of desk space and $$ too.)

I tried to cat both devices, and they're both picking up my mouse movement, although I don't know why. I assume it's safe to delete the one not used in your XFree86Config.

as for the gpm, I heard xdirectfb doesn't work well with it. But I can still use the middle click to copy and paste.

btw, do you get some black or white horizontal broken lines when you scroll a webpage? It only happens when I scroll down but not up. It's kind of weird. I'm using the vesafb driver.

Thanks. I tought both devices were equivalents. I don't have a USB mouse, so I know which one to delete now.

I too have a KVM switch, altough it's a rotary mechanical one, not too ps2 friendly. But it does save space (I have 5 PCs running side be side, only one set of KVM).

Graphicaly, XDirectFB runs perfectly. The only thing I see is that it runs is a slightly lower resolution than in xfree. I use a framebuffer driver for my card, a SiS630.

Still, I miss the acceleration. Xv does not work. So I use the slow X11/Shm to watch videos and it is just yuk!

Double clicking fixed, as a desktop, it's quite usable.

My pleasure

Nice you have xdirectfb running well. My 2 display cards (one i830M, one GForce 2MX) are not friendly to framebuffer. I couldn't get frame buffer for the i830M, and the rivafb for nvidia gives weird console fonts. Maybe, I will try the fdo xserver, or buy another graphic card (when I got my co-op job

)
