I need some help with gfxterm

I was exploring the new video subsystem of GRUB2 (1.94), I followed the
instructions in GRUB wiki about using gfxterm.
This what I did:
	insmod video
	insmod vbe
	insmod font
	font (fd1)/unifont.pff
	insmod gfxterm
	set gfxmode 1024x768x32
	insmod terminal
OK, no errors till now, then:
	terminal gfxterm
here I got that error:
	error: Can't locate valid adapter for mode
and nothing changes.
BTW I'm trying this under qemu.

Hi,

Well, perhaps QEMU just doesn't support that mode...

I tried this sequence with exception (set gfxmode=1024x768x32) in VMWare
and it works nicely. You can specify "set gfxmode=1024x768" to auto
detect best color mode.

You can use vbeinfo module to determine available modes.

insmod vbeinfo
vbeinfo

Thanks,

Thanks for the tip, "set gfxmode=1024x768" works fine. I want to load
these modules in "grub.cfg" file, puting them in the top of the file
doesn't work but making a menu entery that load them works fine, is
this normal ?

Now I'm able to display menu enteries in Arabic. Although grub2
deosn't support RTL nor Arabic shaping, a quicke workaround is to
store the Arabic text in grub.cfg already Shapped by using a tool like
fribidi2 (cvs branch) or "mu"  [ftp://foolab.org/tmp/mu-fribidi.zip]

$ mu < grub.cfg > grub_ar.cfg

then coping "grub_ar.cfg" to grub/grub.cfg.

Here a screenshoot without RTL and shaping

, and this one with
[http://khalid_hosny.manalaa.net/files/khalid_hosny/images/grub2.png].
Also I wrote a mini-howto in Arabic
[http://khalid_hosny.manalaa.net/grub2_arabic_howto] if any one
interested
