I have "evdev" + "radeon vesa" in 'make.conf'. 'xf86-video-ati/vesa' are installed, as is 'xorg-server' + all its requirements ("dependencies"). > There should be a fb0 device listed: > $ ls -l /dev/fb* > crw-rw---- 1 root video 29, 0 Jun 14 08:52 /dev/fb0 ANB5 has /dev/fb0 /dev/dri/card0 with 660 permitions, ANB6 hasn't (those are my names for the present + new machines). > You'll also need to have emerged a Desktop Environment > or at least a window manager: https://wiki.gentoo.org/wiki/Window_manager I've installed 'twm xterm' to test X for now. I will install KDE for regular use later. '.xinitrc' is #xscreensaver & numlockx exec dbus-launch --exit-with-session /usr/bin/twm ie the same as in ANB5, but substituting Twm for Plasma. 230614 Jack wrote : > what does /var/log/Xorg.0.log show ? It has these errors (EE) in the X log file : Failed to load module "fbdev" (does not exist) Open /dev/dri/card0 : no such directory or file VESA (0) : cannot read int vect Screens found, but none has a useable configuration Do I need 'fbdev' or 'card0' ? Whatever is "int vect" ? When I try to 'startx' as user, the log file is in ~/.local/share/xorg , which is also where it is in ANB5. When I try 'Xorg -configure', it produces nothing of use & dumps it in my home directory (ugh). I can probably cut the Gordian knot by emerging Xorg-server with 'suid'. How insecure is that for a single-user system in a house ? The Elogind approach has worked in ANB5 since Aug 2020. I can't make much of a useful comparison between the 2 machines, as ANB5 dates from 2015, ie long before the 'elogind' affair in 2020, & it has Nvidia graphics, whereas ANB6 has cutting-edge AMD. BTW System Rescue + Mint (live USB) load modules for AMDGPU, which seems to be the latest graphics offering ; I need to find some firmware to get it to work (enabling AMDGPU in the kernel causes the boot process to stall with a message re missing firmware). There are in fact 2 graphics tools in ANB6, one in the CPU (AMD), the other on the Mobo (Gigabyte). How can I tell which one the machine is trying to use ? I will continue to poke around, but further advice is very welcome. Please read my comments above carefully (smile). -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
