When I start boot into OS in text mode with BIOS Legacy mode,it is very slow display for example do type cmd: cat /proc/cpuinfo ,but I had tried add a GRUB_CMDLINE_LINUX=”vga=normal” in /etc/default/grub. It can be normal display
My config on the server :
OS ver:Ubuntu 16.04.x server w/o GUI
VGA: onboard AST2x00 w/o install expansion vga card
Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.
To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).
Sorry about the noise!
