Troubleshooting Workstations and Desktops#
Unable to access the BIOS on a Vector desktop with a WRX80 motherboard when it's connected to a 4K monitor.#
If you have a Vector desktop with a WRX80 motherboard and a 4K monitor, when the system boots, the monitor should display the ASUS logo screen; however, it does not show the prompts to access the BIOS. If you press F2 to access the BIOS, the monitor continues to not display the BIOS prompts until after the system restarts. The system boots normally if you don't interact with it, but the video only displays when the Ubuntu OS boots successfully.
You can determine whether your system has the WRX80 motherboard by running:
Your system has a WRX80 motherboard if the command returns: Product Name: Pro WS WRX80E-SAGE SE
The best solution at this time is to switch to a non-4K monitor, like 1080p.
No audio from aux ports on Vector One#
Known issue with Ubuntu 22.04#
A bug in Ubuntu 22.04 can cause the front aux port to not recognize audio devices on some Vector One desktops. This issue is resolved in Ubuntu 24.04; however, Lambda Stack does not yet support this version. Once Lambda Stack moves to Ubuntu 24.04, this issue should be resolved.
Test the rear audio port#
If your machine does not recognize audio devices connected to the front aux port, try using the rear audio port, which is lime green in color. If you still experience audio issues with the rear port, here are some further steps you can take:
Update packages and drivers#
Install the latest software packages and device drivers by running the following command in the terminal:
After the system restarts, test the aux ports again to see if the issue is resolved.
Reinstall audio packages#
If the issue persists after updating the drivers, try reinstalling the audio packages using the following commands:
sudo apt-get -y install --reinstall alsa-base alsa-topology-conf alsa-ucm-conf alsa-utils gstreamer1.0-alsa:amd64
sudo apt-get -y install --reinstall libasound2 libasound2-data libasound2-plugins
sudo apt-get -y install --reinstall gstreamer1.0-pulseaudio:amd64 libpulse-mainloop-glib0:amd64 libpulse0:amd64 libpulsedsp:amd64 pulseaudio pulseaudio-utils
Check the motherboard HD audio cable connection#
Reseat the HD audio cable connected to the front audio port on the bottom-left of the motherboard and make sure the cable is securely connected.
Refer to the image below for the loaction of the HD audio cable port on your motherboard, labelled JAUD1:
