 I tried this solution, but it didn't work, it keeps jumping to the dialog box: "Authentication Required PolicyKit1 KDE Agent, System policy prevents Wi-Fi Scans".

[12:02] <BluesKaj> Hi all
[15:25] <Drew50> Made a USB boot for kubuntu 23.04.  Had to use the "safe graphics" mode to install on an old Polywell i7 CPU 860 (64 bit).  The Polywell only has a DVI output which I convert to HDMI for the monitor input.  Graphics worked fine for the install but now when I boot I get these error messages:
[15:28] <Drew50> No server specified, no suitable video mode found, no video mode activated and the monitor gives me a "no HDMI signal from device.  Then the screen goes black.  I tried all the video options in the boot menu (auto, Ext Pci E Graphics (PEG) and Ext Pci graphics) But no change in the video output.
[15:38] <diogenes_Vx15> Drew50, does it boot into Wayland or X?
[15:39] <Drew50> How can I tell?
[15:40] <diogenes_Vx15> Drew50, when you get to the login screen
[15:41] <Drew50> I don't get a login screen since there is no video output.
[15:42] <Drew50> All I get is the three error messages and the monitor goes blackl
[15:42] <diogenes_Vx15> Drew50, so no video output comes right after BIOS screen? or it doesn't come up at all?
[15:42] <Drew50> I can work in the BIOS, but after that nothing comes up.
[15:43] <Drew50> I tried all the video options in the BIOS
[15:44] <Drew50> video output works for BIOS but not for kubuntu.
[15:45] <diogenes_Vx15> Drew50, that requires more troubleshooting but i'm a bit busy now.
[15:45] <Drew50> Thanks for checking.
[15:46] <Drew50> I'll try the "ask ubuntu" forum.
