Debian User Forums

Bump? Really, no one can help with this?

Change GDM3 Theme In Debian 12? I actually want to just change the GDM3 user name list colors, but from what little information there seems to how to do this in Ubuntu... I need change the default theme? Many references for other distributions reference a GDM css file? No luck find that in Debian 12?

Linux P2P over USB? This is file transfer from two separate non UI based Linux systems. I have the correct cable, a USB to USB, isolated, null modem cable. However, I can't seem to find any instructions on how to setup P2P communication. I cannot use an ethernet cross-over solution, it must be USB t...

I have the right cables now, so working on the software implementation, is to use a USB port as a mimic of an RS-232 port. The trick is to get a terminal (getty session) linked to the USB port. Will post back once I have this working.

I am new to the ways of apparmor, once had to create selinux profiles in CentOS and RHEL, so I think I understand what is going on with... [ 51.129117] audit: type=1400 audit(1669406835.918:23): apparmor="DENIED" operation="mknod" profile="msmtp" name="/var/log/msm...

Guys, Thanks for the reference links, that is a big help. I am quite familiar with the typical GND, TX, RX Pin to USB serial cables/adapters that various micro-controllers can use to connect to PCs, for example ESP8266 modules. But my old PC has a DB-9 serial port (likely RS-232 right?), and USB por...

Yeah, that would work, but I have been playing with the refresh timing CVT settings and the refresh rate, and that seems to sometimes work depending on the monitor. For example, my HDMI monitor is 60 Hz, but when I force the configuration to 60.02 it does adjust a bit. Which is odd that a digital ED...

How to change the color of the highlighted user in the login-dialog-user-list in GDM? As I understand it, this can be done in Ubuntu via the following method... # nano /usr/share/gnome-shell/theme/ubuntu.css .login-dialog-user-list { spacing: 12px; padding: .2em; width: 23em; } .login-dialog-user-li...

Have a PC, and want to use a USB to Serial connection, rather than a monitor. The PC happen to have a traditional DB-9 serial port as well as USB ports. How do I configure Debian on the PC to use the serial port or one of the USB ports to a serial connection, rather than use a monitor via the VGA po...

Yeah, from a technical perspective, would love to figure out why it was not working, but would never be practical perspective as I noted.

Overscan issue only in terminal console session? Hardware has an older ATI radeon 4290 GPU on motherboard. The GRUB resolution is correct, the initial screen after GRUB is right, the GDM3 and Gnome Desktop are correct, set to 1280x1024@60.02. However, when I jump to the terminal console screen (CTRL...

Decided using a dedicated interface made more sense than trying to chase this down. Using a separate management rail or interface is a best practice anyway, isolating management/control of KVM host from VM traffic.

Installed QEMU KVM Setup Bridged Networking But Now Can't use SSH? Not sure how to resolve this. What is odd is that routing is working, I have a route to the gateway, I can use the Browser in Gnome to get to Google, etc. So the NIC appears to be working. Connection Manager shows that the bridge, br...

What process actually displays 'login as:'? Is it getty.service or login (binary)? I looked at the sources (at least what I think are the sources) for login and getty.service and I don't see the prompt string? Am I looking in the wrong source files?

How to disable Greeter Screen Saver? This is not a question about disabling the desktop screen saver, but about the screen saver that engages when the Gnome greeter is active, such as at login. We run a lot of VMs, a screen saver on any VM is useless waste of cycles, including the one that actives i...

How does one suppress the following warning? [drm:radeon_vga_detect [radeon]] *ERROR* VGA-1: probed a monitor but no|invalid EDID Everything, in reference to video card, resolution, etc. is working fine. But my syslog is getting flooded with the above messages. The video card is on-board video, ATI ...

I am new to mdadm use, but as I understand it, if you don't define the array in the mdadm.conf file, you make life more difficult, I would say. Just about very example i have looked at, all set the expectation that you need to add the array definitions to the configuration file. But you don't after ...

Cool, thanks. I decided to use the 'autostart' directory for now, that works for running stuff at session start, not as elegant or specific but gets the job done.

Odd, I can't seem to get XRDP to work on Debian 11 at all with GNOME, if I switch to say Xfce works fine. I believe the issue might be the polkit rule, because I see the following in the auth.log...
