uvesafb not showing proper resolutions

I'm trying to get uvesafb to work, however, it does not list the proper resolution for my monitor:

I have a 1080p monitor that is capiable of 1920x1080-32

$ cat /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes
640x400-8, 0x0100
640x480-8, 0x0101
800x600-8, 0x0103
1024x768-8, 0x0105
1280x1024-8, 0x0107
320x200-16, 0x010e
320x200-32, 0x010f
640x480-16, 0x0111
640x480-32, 0x0112
800x600-16, 0x0114
800x600-32, 0x0115
1024x768-16, 0x0117
1024x768-32, 0x0118
1280x1024-16, 0x011a
1280x1024-32, 0x011b
320x200-8, 0x0130
320x400-8, 0x0131
320x400-16, 0x0132
320x400-32, 0x0133
320x240-8, 0x0134
320x240-16, 0x0135
320x240-32, 0x0136
640x400-16, 0x013d
640x400-32, 0x013e
1600x1200-8, 0x0145
1600x1200-16, 0x0146
1400x1050-8, 0x0147
1400x1050-16, 0x0148
2048x1536-32, 0x0152

any ideas on how i can get the proper or even any 16:9 resolutions?

Thanks!

Re: uvesafb not showing proper resolutions

You don't. You can only use what's in the vbios of your graphic card. If the resolution you want isn't in there, you're out of luck.

that was my suspicion.  thanks for confirming

One last question -- what about using something like the 915resolution hack?

Re: uvesafb not showing proper resolutions

If you have intel graphics, why are you messing with uvesafb? Intel has a KMS driver.

If you don't have intel graphics, i915resolution won't work because it is, as the name implies, for intel. It's a relic from the pre-KMS days, totally obsolete nowadays.
