Hi all, has anybody successfully configured a graphical grub-2.00 boot in Crux 2.8 - with a nice background image, a correct font and all? I gave up after 2 days of experimenting and approx. 100 reboots. Either I got an image, but with an ugly frame around it (the font missing the line and corner characters), or I got a text mode menu anyway. I also spent some time in searching the web for a grub2 documentation, but it seems that any good documentation about grub2 is automatically Ubuntu-specific. So if anybody has such a configuration, I'd appreciate if he could send me his grub.cfg and etc/default/grub. - Thanks in advance!
Hi, Bernd, This is indeed possible with a little bit of work. Here's an example grub.cfg: ----- set default=0 set timeout=5 set menu_color_normal=white/black set menu_color_highlight=white/blue loadfont /boot/grub/unifont.pf2 set gfxmode=1024x768 insmod all_video insmod gfxterm terminal_output gfxterm insmod jpeg background_image -m stretch /boot/grub/artorias.jpg # set the root variable search --fs-uuid --no-floppy --set root aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee menuentry "CRUX 2.8 x86_64-multilib (3.5.4)" { set gfxpayload=keep linux /boot/vmlinuz-3.5.4 root=/dev/sdc2 ro quiet } menuentry "CRUX 2.8 x86_64-multilib (3.5.4) single-user rescue" { linux /boot/vmlinuz-3.5.4 root=/dev/sdc2 ro single } ----- First things first, the unifont.pf2 file is created by downloading unifont in BDF format from http://unifoundry.com/unifont.html, then converting it via grub-mkfont: $ wget http://unifoundry.com/unifont-5.1.20080820.bdf.gz $ gzip -d unifont-5.1.20080820.bdf.gz $ grub-mkfont -o unifont.pf2 unifont-5.1.20080820.bdf $ sudo install -o root -g root -m 0644 unifont.pf2 /boot/grub/ You can use a different font if you like, this is the one I use. Next up, 'set gfxmode=1024x768' sets the video mode as you might guess. The modes this command supports are the VBE modes supported by your video card's BIOS, NOT the modes that your X.org driver can support! If you need a list of those modes, at the grub menu press 'c' to get a command prompt, then type 'vbeinfo' and grub will show you the modes that are available. If you set a mode that isn't supported grub2 will switch to one that is, in my experience. For example, if I use 'set gfxmode=1920x1080' it will end up using 1280x1024 instead. Even though 1920x1080 is the native resolution of my monitor, it is NOT supported by the video card's VBE BIOS. 'insmod all_video' loads grub2's 'all_video' module. You could probably use 'vbe' or something here, I didn't test that. 'insmod gfxterm' and 'terminal_output gfxterm' load and enable grub2's graphical display support. 'insmod jpeg' loads grub2's jpeg module. If your splash is in one of the other supported formats, load that module instead. The supported formats seem to be jpeg, png, and tga. 'background_image -m stretch /boot/grub/artorias.jpg' loads the image itself. There are two options for the mode (-m), 'stretch' and 'normal'. 'stretch' does what you'd expect, I believe 'normal' just aligns the image to the top right corner without scaling but I didn't test that either. The rest of the options are not related to the graphical splash setup. Hope this helps. Matt
