no text mode image through hdmi during installation

tvidal · 2020-06-18 18:03:59

Hi,

After a few years using debian/kde, I have decided to try arch.
The installation on a qemu vm was straightforward, installed kde and after troubleshooting a few things I have decided arch is the way to go.

I dumped (dd) the iso to a USB stick, booted from it.
I can see the arch linux grub boot menu, I choose "Boot Arch Linux (x86_64)"
Next, the screen is cleared, the message "Probing EDD (edd=off to disable)... ok" is shown.

Then the screen goes blank, the TV screen saver kicks in, as if there was no video signal (I use an LG 43" 4k TV as a monitor).

I've searched for posts with similar issues, but most are related to users having a discrete video card and the internal intel video adapter, which is not my case.
I have an Intel i7 5820k X99 processor which does not have an embedded video card and a MSI NVidia GTX970 discrete video card.

This is the output of xrandr from a terminal running inside debian

Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm
   3840x2160     60.00*+  59.94    50.00    29.97    25.00    23.98  
   4096x2160     59.94    50.00    29.97    25.00    24.00    23.98  
   1920x1080    119.88   100.00    60.00    59.94    50.00    29.97    25.00    23.98    60.00    50.04  
   1360x768      60.02  
   1280x1024     60.02  
   1280x720      59.94    50.00  
   1152x864      60.00  
   1024x768      60.00  
   800x600       60.32  
   720x576       50.00  
   720x480       59.94  
   640x480       59.95    59.94    59.93  
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DVI-D-0 disconnected (normal left inverted right x axis y axis)

Which makes me thing, it's either in an unsupported text-mode in HDMI-0, which is unlikely, as I don't have this problem when using debian's single-user/recovery mode
OR
It's switching to one of the disconnected video-outputs.

I know the system is working, because if I run "reboot", the computer reboots after a couple of seconds.

Hence my question: Is there any argument I can provide to grub during boot time or maybe modify the installation media on the USB to force video output to HDMI-0?

Worst case scenario, is there a way to switch the video-output to HDMI-0 after the screen goes blank, if I blindly type a command without the visual feedback?

Thank you in advance.

That was spot-on, thank you so much.

For future reference, adding nomodeset to the syslinux boot cmdline has solved the issue.
