Text-based console size is 48x160 after updating to RHEL 6.8

Latest response

Hi.

After updating my RHEL 6 virtual machine up to RHEL 6.8, the text-based console has 48 rows and 160 columns.

I have tried to use the "vga=" kernel option in the grub.conf file but it is useless because it is the DRM kernel module which resizes the screen:

[drm] Screen Objects Display Unit initialized
[drm] width 1280
[drm] height 768
[drm] bpp 32
[drm] Fifo max 0x00040000 min 0x00001000 cap 0x0000077f
[drm] Using command buffers with DMA pool.
[drm] DX: no.
fbcon: svgadrmfb (fb0) is primary device
Console: switching to colour frame buffer device 160x48
[drm] Initialized vmwgfx 2.9.0 20150810 for 0000:00:0f.0 on minor 0

How can I set my console back to 25x80?

Thank you

Hi,

Have you tried the 'nomodeset' and 'video' options? outlined in this solution: https://access.redhat.com/solutions/81423

I have tried video=640x400 but it does not work.

If vga=ask is used, a list of codes are displayed and selecting 640x400x8 mode changes the console size but not as expected -- the text-based console size is 100x37.

Definitely vmwgfx.enable_fbdev=0 does work.
