Linux Mint isn't detecting the second screen properly.
Linux Mint isn't detecting the second screen properly.
Hello, welcome to Linux! You're experiencing issues with your second display not working after installing Linux Mint Live System. It's possible the installation wasn't complete or there might be compatibility concerns. The connection via USB-C dongle should help, but ensure it's properly seated and powered. If the problem persists, check your display settings or contact support for further assistance. Thanks for reaching out!
mint@mint: The command encountered an issue retrieving the gamma size for the default screen output. It reported a minimum resolution of 1920x1080, which matches the current display settings. The maximum allowed is also 1920x1080, but the system detected a default primary size of 1920x1080 with specific dimensions.
Using Linux Mint Live can sometimes lack essential drivers, leaving only basic functionality. A full installation may help resolve certain issues. Look for official Linux driver sources for your device. If no official drivers exist, try third-party alternatives. Be aware that some laptops need special USB-C solutions or have ports that only support data without display output. Refer to HP support threads discussing Display output via USB-C on Pavilion x360 and EliteBook models.
After starting Linux, the system prompts you to check your video drivers in the top-right corner. When you click the launch driver manager button, it confirms everything is up to date. To properly install a graphics driver, ensure your hardware is recognized and consider updating your system packages or using the appropriate tools for your specific chipset.
You're running the Linux kernel. Type "uname -a" to confirm details about your system. AMD support exists within the kernel using the Mesa stack, and it remains compatible as long as updated distributions are available.
Here are some possible approaches:
1. Open terminal and use "xrandr --auto" to enable the desired output and set the best resolution.
2. Install the latest kernel version and then run "xrandr --auto" – it sometimes works. For AMD R7 4000 starting from 5.7.8, try it; however, GPU/APU detection may still be incomplete.
3. Check if the dongle includes a direct power plug – connect AC directly to it.
Hard solution: This dongle isn't ideal for Linux. The worst case is missing USB-C to HDMI support on the GPU or chipset drivers (CPU may work, but other parts might not).
The output shows your system details and some hardware status. The xrandr command failed because it couldn't determine the size of your graphics card. To fix this, ensure your graphics card is properly detected or try a different method to list it. Regarding the kernel, you can install the latest version on Mint through the official repositories, but kernel updates may be limited to the distribution itself. For the Dongle, since it doesn’t have a power plug, make sure it’s connected correctly and compatible with your system. If needed, check Amazon for similar models or contact support for alternatives.
