I assume you got the same result using the default 5.15 kernel? Most of the time, the laptop's HDMI port is connected internally to the Nvidia GPU, so you need the Nvidia driver installed. The inxi output shows it is either not installed or your system is in Intel Power Saving mode. If you have alre...

The info extracted from the laptop display panel's EDID does not list the 1920x1200 resolution, so it is not being read correctly by the Linux kernel driver or is corrupted. Try using these commands to force that resolution: xrandr --newmode "1920x1200x59.95" 154.00 1920 1968 2000 2080 120...

The Select All feature no longer works in Mint 21. However, you can easily select all the text by clicking and holding with the mouse button or pad at the beginning of the first line. Move down to the bottom and release the click. Right click in the Terminal window and select Copy . Or use the comma...

Use the command xrandr --verbose and post the output.

After booting to the desktop, use the 3 xrandr commands. Open the Display program and click the Apply button. If it is grayed out, then first select the previous resolution and click Apply. Then select the new resolution and click Apply again, to save the setting to the cinnamon-monitors.xml file. O...

Also if i understand what you were somehow doing, were u making a custom EDID for my monitor based on the specs that i have given you and put that on the boot so that it applies before it start? I got the laptop display panel's EDID from the xrandr --verbose output and used Custom Resolution Utilit...

this is the msg when i did dmsg grep | edid [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-6.5.0-1004-oem root=UUID=a0e93505-a7fb-4ab1-9042-78451394c129 ro quiet splash drm.edid_firmware=edid/edid.bin [ 0.024344] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.5.0-1004-oem root=UUID=a0e93505-a7...

Do you think changing to wayland would help? It may, but try this last method of editing the EDID first. Download the edid.zip file below and extract the edid.bin file. edid.zip Create an edid folder and move the edid.bin file to it, but change your-user-name to your actual user name: sudo mkdir /l...

Use this command to create an xorg.conf file and open it for editing: sudo touch /etc/X11/xorg.conf && xed admin:///etc/X11/xorg.conf Add these lines: Section "Monitor" Identifier "Monitor0" HorizSync 24.0 - 229.0 VertRefresh 40.0 - 120.0 Modeline "2880x1800R" 6...

I also tried to do the cvt but when i added it as an output it just blackscreen... I assume you used cvt 2880 1800 120 to create a modeline? For high resolution and/or high refresh rate modes, usually reduced blanking modes are required, which reduces the bandwidth requirements for the video signal...

I looking to see how I can turn on g-sync in linux for my monitor. I have a BenQ EL2870U with free-sync. Your monitor is not listed on this G-Sync Compatible list: https://www.nvidia.com/en-us/geforce/products/g-sync-monitors/specs/ However, it may work if you follow the instructions in this articl...

I don't know if the method used by user Smackd0wn will work for you. I tried testing that method but can't confirm it works because I don't have your video problem. I was hoping to see a confirmation message in the logs that the method was successful. Here is what I get from the dmesg log after usin...

These sections from your output are identical to what user Smackd0wn listed in his post in this article: https://gitlab.freedesktop.org/drm/intel/-/issues/7709 Child device info: Device handle: 0x0008 (LFP 1 (eDP)) Device type: 0x1806 (unknown) Child device info: Device handle: 0x0080 (LFP 2 (eDP)) ...

To prevent fallback mode, you can try adding this line to the ServerLayout section of the xorg.conf file, to enable Xinerama: Option "Xinerama" "1"

The log shows the Nvidia-470 driver loaded successfully. An explanation for that is there are 3 chip IDs for the GeForce GT 740M. Evidently one of those GPU chips must be a newer architecture that supports a newer driver. I've seen this with other GPUs and finding detailed info on this is often diff...

Use this command and post the output: xrandr --verbose The Nvidia-470 driver doesn't support the GeForce GT 740M. Click the Search button: https://www.nvidia.com/Download/Find.aspx?lang=en-us Use this command to upload the Xorg.0.log file to terminal.com pastebin: cat /var/log/Xorg.0.log | nc termbi...

To get two identical or similar GPUs to work, you also have to enable Xorg's Xinerama feature. In the Nvidia Settings utility, on the X Server Display Configuration page, click the Advanced button. However, I don't know if the Xinerama option will appear if no monitor is connected to the second GPU....

I think every Screen section requires a Monitor section to go with it, with the exception of the config file used with a laptop with Optimus support. So you would need this, but I don't know it there will be a problem if no second monitor is connected. Section "Monitor" Identifier "Mo...

The log shows this repeating message: NVRM: This PCI I/O region assigned to your NVIDIA device is invalid: NVRM: BAR0 is 0M @ 0x0 (PCI:0000:01:00.0) A similar message is reported In this topic in the Nvidia Developer Forums for Linux Graphics. User generix says Please check the bios for an option li...
