[nouveau] Laptop video problem

[Karim BAKKAL]

After a fresh install, the system goes to sleep mode in place of showing logon display. After waking up, the screen stay black but login action and shutdown button seems to work so there's no video on laptop screen (LVDS-1).

When i connect an DVI-I monitor before starting, the computer doesn't go in sleep mode at startup. I can see the logon on external monitor but there nothing on internal monitor.

I can use the two monitor when i use those commands:
xrandr --output DVI-I-1 --mode 1400x1050 --primary
xrandr --output LVDS-1 --mode 1440x900 --right-of DVI-I-1 --crtc 0

LVDS-1 is reported as "unknown connection" in place of "connected" or "disconnected".

Xorg0.log report that the internal monitor is disconnected :
[ 31.856] (II) NOUVEAU(0): Output VGA-1 disconnected
[ 31.856] (II) NOUVEAU(0): Output LVDS-1 disconnected
[ 31.856] (II) NOUVEAU(0): Output DVI-I-1 connected
[ 31.856] (II) NOUVEAU(0): Output TV-1 disconnected

If you can then please try Ubuntu 20.04:

  https://ubuntu.com/download/desktop

or try Xubuntu 20.04:

  http://cdimage.ubuntu.com/xubuntu/releases/20.04/release/

and tell us if the problem still occurs in that version.

I can't try Ubuntu 20.04 or Xubuntu 20.04 because it's a 32 bits CPU.

I had similar problem at startup with Debian buster i386 but i'm waiting an other hard disk to say if it was exactly the same thing or not.
