How to change the framebuffer resolution on tty1-4

Mr. Swillis · 03-07-2012, 12:56 PM

Hey Everyone,

I just setup a new system with CentOS 6.2 that I plan on rolling out an old ncurses based POS system on. I've got it working fine in 5.x and everything is fine so far in 6.2, except the default resolution on ttys 1-4 is way higher than the app is expecting.

It's trying to use a default terminal size of 80x24, so it looks all messed up on the higher resolution screen size. Anyone know off hand where I can adjust this? The default in 5.x seemed to be fine.

Thanks!

The high console resolution is most likely caused by newer video drivers with activated kernel mode setting. If that system isn't running a GUI it is safe to disable kernel mode setting, either blacklist the video driver or use the kernel command nomodeset in your bootloader.

Thanks for the responses! I found the "vga=xxx" line in a google search, but it didn't work for me. The "nomodeset" option did the trick!
