The thread "Problems with kernel-3.10.0-693.5.2.el7.x86_64? reminded me
that I have a similar problem but on the latest CentOS 6 kernel I?ve been
meaning to report. Here is the relevant system information:
Linux ssg003.bose.com 2.6.32-696.13.2.el6.i686 #1 SMP Thu Oct 5 20:42:25 UTC

I have about 100 Dell desktops deployed with CentOS 6 all using the built-in
motherboard graphics. But on a Dell Optiplex 5050 with an Intel(R) Core(TM)
i7-7700 CPU @ 3.60GHz CPU and the above graphics card, the X11 login screen is
all distorted and unusable. There is a simple solution: if I remove the
"vga=0x31b? parameter from the kernel boot command it works just fine.
However, I would prefer to have a usable alternate console on our 1900x1200
monitors, but any value I tried for the vga parameter results in a distorted
login screen.
Any ideas what may be causing this? This is only an issue on the very latest
chipset. On the next most recent Dell desktops we have (Intel(R) Core(TM)
i5-4590 CPU @ 3.30GHz) I do not have this issue. Here is the VGA controller
info:

Does anyone else have a similar issue and found a better solution?

Am I the only one seeing this issue? Or is it that so few people are still running CentOS 6.x? Quick summary, on a very recent Dell motherboard using the on-board vide and booting the latest CentOS 6 kernel with the ?vga=xxx? parameter set to any non-default value results in unusable X11 graphics.

All of them have decent video cards, neither of them uses on system board (aka "motherboard") of on CPU die video. I know this will not help to solve your trouble...
