[Bug 1868473] Re: 20.04 Install screen corrupt on Lenovo P73+NVIDEA RTX-5000

Wed Mar 25 08:11:42 UTC 2020

The installation media uses the open source driver "nouveau" for nVidia
cards, and recent GPUs are not always well supported. It is recommended
to boot in "safe graphics" mode, then select "Install 3rd party drivers"
during installation to install latest nVidia proprietary drivers for
your card.

To boot in "safe graphics" mode, if you're booting with UEFI, select an
entry with "(safe graphics)" from the boot menu. If you're booting in
legacy mode, press any key when the purple screen with the small
keyboard appears  to display the boot menu, the n select an entry with
"safe grpahics".

I hope this helps.

Title:
  20.04 Install screen corrupt on Lenovo P73+NVIDEA RTX-5000

Status in casper package in Ubuntu:
  Won't Fix

Bug description:
  Hardware: Lenovo P73 with NVIDEA RTX-5000 QMax

  20.04 Daily Build install.

  On using the USB drive for a new install the screen is corrupt. This can be worked around by:
  1. Waiting for Focal Fossa to give the sound showing the splash screen.
  2. Closing the screen so it goes into sleep mode.
  3. Open the screen and hit the power button to wake the system.
  4. Wait a second or two and screen loads correctly and the rest of the install works beautifully.
