Comment 108 for bug 1724639

confirming that on TOSHIBA Portege, the bug has disappeared after upgrade to 18.04 beta with kernel 4.15.0-13.

The line
GRUB_TERMINAL=console
is not needed anymore and X starts OK, and the error message I mentioned above is not reported in the log.

I am getting an error message in dmesg though:

[ 24.576771] [drm:intel_enable_lvds [i915]] *ERROR* timed out waiting for panel to power on

maybe because 1000 msec delay that is in the kernel source is not sufficient, who knows.

Also, lxrandr is unable to save and then next time properly load settings. I have read somewhere that it may be because the modes are somehow not properly reported during start.

Also, plugging the monitor to VGA requires restart before X is shown there, even though it is recognised after plugging in (i.e. with randr output)

And also, nothing is shown on the screen during grub booting, no menu, graphics screen, or whatever, but maybe that is to be expected, I do not know.
