nanogui: Thread: About running the demos on Linux

Hi. I'm new to the list and microWindows.

I have downloaded the 0.87 source into my Linux box operating
Red Hat v6.2. After some tuning with 'src/configure' I could compile
the entire library demo, but I have a great pain to run the demos.

Every time I run the demo (in src/bin directory), I get the following
message complaining about display:

Error opening /dev/fb0: No such device
Cannot initialize screen: No such device

I tried the every 4 display option (frame buffer, SVGA, HWVGA, X11)
but failed to execute the demos.

Can anybody enlighten me? It's eaten up my whole day!
Thanks in advance.

You must choose FB if you have a FB device which you don't seem to have
(/dev/fb0 doesn't exists)
Choose X11 instead. (edit the config file and set the GRAPHIC SUBSYSTEM to
X11)

You haven't any FB device setup. Recompile the kernel and enable it if you
want to have one.

X11 should work èretty well (after having startx :-) )

Hope this helps
