Virtualbox
From My Admin Page
- Setup various Desktops Centos 7 (afterwards, run "systemctl set-default graphical.target")
- To install Centos/RH Guest additions, the OS needs
- yum -y install gcc kernel-devel bzip2 perl
- increase CLI resolution for Centos VM (for 2.6.x kernels) (from HERE)
- in /etc/grub.conf add to the end of the "kernel" line "vga=<xxx>" where xxx equals
Colour depth 640x480 800x600 1024x768 1280x1024 1400x1050 1600x1200 8 (256) 769 771 773 775 15 (32K) 784 787 790 793 16 (65K) 785 788 791 794 834 884 24 (16M) 786 789 792 795
- For newer kernels (3.x) (see HERE)
- Newer kernels use KMS by default, so you should move away from appending vga= to your grub line as it will conflict with the native resolution of KMS. However, it depends upon the video driver you are using: the proprietary Nvidia driver doesn't support KMS[1], but you can work around it. You should be able to get full resolution in the framebuffer by editing your /etc/default/grub and making sure that the GFXMODE is set correctly, and then adding a GFXPAYLOAD entry like so:
- GRUB_GFXMODE=1680x1050x24
- # Hack to force higher framebuffer resolution
- GRUB_GFXPAYLOAD_LINUX=1680x1050
- Remember to run sudo update-grub afterwards.
