Re: [SOLVED] Laptop External Monitor - Low resolution

So it appears that everything is working correctly. I assumed you were getting the greenish background and stripes when opening certain programs, but it’s only when you take pictures using a cell phone. I can’t explain the physics as to why that happens but often when I have used a camera to take pi...

Re: Laptop External Monitor - Low resolution

I see these stripes when I open any folder or program only on coloured items. But the Displays program’s colors look normal without any stripes. Unfortunately, you don’t have another PC to connect the monitor to for testing. Under Desktop Settings > Windows , change the setting for the Window Manag...

Re: Laptop External Monitor - Low resolution

Looking forward to your advice regarding the colour stripes Are you seeing the stripes only in some open program windows? The two images you posted of firefox and nemo don’t look like screenshots. The Displays program picture you posted is a screenshot and looks normal. Get the Dell P190S user guid...

Re: Laptop External Monitor - Low resolution

I can log in without any problems. In Monitor Preferences (Displays), the 1280x1024 is the active one but the resolution problem insists. I don’t understand what the problem is. Looking at the picture in your link (size of panel and Display program window), it looks like a 1280x1024 resolution is b...

Re: Laptop External Monitor - Low resolution

I suspect your particular GeForce 7600’s video BIOS does not support the 1280x1024 vesa mode. It’s up to the manufacturer as to what vesa modes are supported. At least the 1024x768 mode will look a lot better on the Dell monitor because the 4:3 aspect ratio is very close to 5:4. On the Acer, the ima...

Re: Laptop External Monitor - Low resolution

Changing monitors will not allow the nouveau or nvidia driver to be used; it was to hopefully allow for the monitor’s maximum resolution to be used. I’m convinced you were using the vesa driver when the laptop’s screen was working. This was verified when running the Live Mint USB and re-installing M...

Re: AMD GPU doesn't work properly with 4K monitor

What is the model number of the Dell monitor? Are you sure it supports a 3840x2160 @60 Hz resolution? Do you have a Windows PC the monitor can be connected to so it can be verified? After extracting the info from the monitor’s EDID, the maximum dotclock (pixel clock) supported is given: Monitor rang...

Re: Setting modified 'xrandr' resolution to stay after boot?

Use the 3 xrandr commands in the Terminal for the 1900x1200 mode. They should also be in the .profile file. Open the Display program and click Apply , which saves the new mode settings in the monitors.xml file. Log out and back in. If that doesn’t work, use this command to remove the monitors.xml fi...

Re: NVIDIA driver installed but not loaded - LM 19.1

Your system has Secure Boot enabled. This prevents the Nvidia driver from loading. Either disable Secure Boot in the BIOS, or if you want it enabled for an added layer of security, then the Nvidia kernel modules that were built during the Nvidia driver installation will need to be signed. Many distr...

Re: Laptop External Monitor - Low resolution

If you look at this article on vesa modes and at the chart under the section: Linux video mode numbers , you will see that your monitor’s 1366 x 768 resolution is not supported by the vesa driver, so the next highest one was selected, which is 1024x768. https://en.wikipedia.org/wiki/VESA_BIOS_Extens...

Re: Laptop External Monitor - Low resolution

My final conclusion is you may have installed the Nvidia driver when the laptop’s screen was still working, but it was not loading. The inxi output is sometimes confusing; the Xorg.0.log file needs to be checked. The vesa driver was probably loading but was able to deliver the laptop’s 1280x800 nati...

I haven’t tested Bumblebee since last year but I just finished some testing and Bumblebee is not working correctly in Mint 19.1. If I find a solution, I’ll contact you with a Private Message. I suggest removing Bumblebee and re-installing nvidia-prime : apt purge bumblebee* primus* and apt install n...

Re: Nvidia drivers problem

Older Intel GPUs continue to use the intel driver instead of modesetting . Your Intel 3rd Generation Graphics must be one of the older ones. If you used the command apt install bumblebee , then all the packages you need are not installed. Besides bumblebee, you need bumblebee-nvidia and primus . If ...

Re: Laptop External Monitor - Low resolution

Mint 18.3 came with the 4.10 kernel, I think 4.10.0-38. You may upgraded from Mint 18 or 18.1, which used the 4.4 kernel.

What instructions did you use to install Bumblebee. It’s more difficult to setup in Mint 19. If you want to continue using it, then nvidia-prime should be removed: apt remove nvidia-prime To open Nvidia Settings when using Bumblebee, use this command: optirun -b none nvidia-settings -c :8 The log fi...

Re: HP ENVY with nvidia and intel gpu's

I followed this article: https://github.com/timrichardson/Prime-Ubuntu-18.04 You didn’t need to use that method; just install the Nvidia driver in Driver Manager. That method was created to allow faster switching of the Intel and Nvidia GPUs. In Mint 18, switching GPUs was fast, about 10 seconds or...
