It appears your machine has two GPUs: * Nvidia GeForce GT 710 * IntelĀ® HD Graphics 2500
but neither are working properly, which is why you are stuck in low resolution. Your Nvidia GPU is not working because the kernel driver ('nouveau') isn't enabled (I don't know why). And your Intel GPU is not working because it has been disabled in your system BIOS. My first suggestion to get the Nvidia GPU working properly is to just install the latest Nvidia driver. You can find it in the 'Additional Drivers' app or via the 'Software & Updates' app in the 'Additional Drivers' tab. Install it and then reboot. If that does not solve the problem, and you can afford the time, then I recommend installing Ubuntu 20.04 instead: https://releases.ubuntu.com/20.04/ This does not appear to be a Xorg bug at all. At most it's a kernel bug in the nouveau driver, but probably not one that needs to be fixed. Please just follow the above instructions. ** Summary changed: - wrong resolution , big desktop pixelized, tabs on mozila crash , system crashes, every time fail to install updates and packages + [nouveau] wrong resolution , big desktop pixelized, tabs on mozila crash , system crashes, every time fail to install updates and packages ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Summary changed: - [nouveau] wrong resolution , big desktop pixelized, tabs on mozila crash , system crashes, every time fail to install updates and packages + [Nvidia GT 710] wrong resolution, no working driver ** Summary changed: - [Nvidia GT 710] wrong resolution, no working driver + [Nvidia GeForce GT 710] wrong resolution, no working driver -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893094 Title: [Nvidia GeForce GT 710] wrong resolution, no working driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
