Dear LiveMedia@FedoraForum:

In Fedora 10 LiveCD, I could set the virtual console resolution with the help of boot option, "vga=kernel_vesa_mode_number". You might notice that I could boot into the virtual console with "vga=0x315" in Fedora 10 LiveCD.
$ su -
# cat /proc/cmdline
initrd=initrd0.img root=CDLABEL=F10-i686-Live rootfstype=iso9660 ro liveimg vga=0x315 3 BOOT_IMAGE=vmlinuz0
# stty -a
speed 38400 baud; rows 37; columns 100; line = 0;

With the same computer, this boot option didn't work anymore in Fedora 11/12 LiveCD as listed in the followings - I did specify "vga=0x315" or "vga=ask" in the kernel parameter but I got a terminal screen size of 64x160, no matter what the vga boot option was. The font size was too small for me.
$ su -
# cat /proc/cmdline
initrd=initrd0.img root=CDLABEL=Fedora-11-i686-Live rootfstype=auto ro liveimg vga=0x315 3 BOOT_IMAGE=vmlinuz0
# stty -a
speed 38400 baud; rows 64; columns 160; line = 0;

Is there a way to Change The Virtual Console Resolution In Fedora 11/12 LiveCD? Can you please let me know what I'm missing?

Thanks LiveMedia@FedoraForum! Hope You Can Help!

Best Regards,
cibalo

The way to set console resolution with modesetting is to use the 'video=XxY' parameter

edit: see also http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d50ba256b5f1478e15accfcfda9 b72fd7a661364

so use 'video=1280x800' for widescreen laptops or 'video=1024x768' or 'video=640x480' etc

If modesetting isn't supported or you disable it (with 'nomodeset' parameter) you get a vesa framebuffer which can then use the 'vga=' parameter

That DOES NOT WORK for me (I want to change the font of the pseudo terminal). Fedora 13 (Gnome) with "nomodset" parameter in Grub.

When I pass vga=parameter, the boot splash screen font increases, however when I enter a tty console (Ctrl+Alt+F2~F6), I have the same console font size and screen res. (1400x1050 on a 15' LCD notebook)

I have followed another thread: http://forums.fedoraforum.org/showthread.php?t=221898

/etc/sysconfig/i18n

SYSFONT="sun12x22"

Not to avail. The font size of the boot splash increases, but as soon as I reach the Fedora login screen and enter a tty console (without login to Gnome), the font is still the same.
