CentOS 7 installation display in slanted

Post by bkshtha » 2017/10/17 08:17:38

Hi All,

I tried clean install CentOS 7 in servers "HP proliant DL380 Gen9", "UCS C240 M4" and "PowerEdge R320".

After Clicking on Intall CentOS 7, Monitor start displayed showing slanted from left to right and cut in two columns in all three servers.

I tried installing CentOS 7 from troubleshooting option choosing "Install CentOS 7 in basic graphics mode" but still not luck.

Any how with hard working, I installed CentOS 7 in slanted display.

Then I connected server remotely with ssh (this way display is normal) and make changes in grub2 as follows:
Added following lines in file /etc/default/grub

RUB_GFXMODE=1024x768x32
GRUB_GFXPAYLOAD_LINUX=keep

then updated the grub with command

# grub2-mkconfig -o /boot/grub2/grub.cfg

rebooted the server. Still no luck and still displaying in slanted form.

Can you please help me out how can i resolve the display in server.

Thank you very much.
