I can see three issues: 1. You're using Ubuntu 16.04. While that is supported, it is not well supported. Please consider trying Ubuntu 20.04 instead: https://ubuntu.com/download/desktop
2. The nvidia driver (when it is working) reports the screen is faulty: [ 19.136] (WW) NVIDIA(GPU-0): The EDID read for display device DFP-0 is invalid: the [ 19.136] (WW) NVIDIA(GPU-0): checksum for EDID version 1 is invalid. Please try to get a BIOS update from Acer to fix that. 3. The Nvidia driver is possibly not installed properly. Please uninstall it completely. Then if the system still doesn't work without it, reinstall it. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1878050 Title: Nvidia GT 240m gives problems Status in xorg-server package in Ubuntu: Incomplete Bug description: Can't install proprietary NVIDIA driver 340.107 X uses software rendering rather than hardware ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3.1 ProcVersionSignature: Ubuntu 4.4.0-178.208-generic 4.4.217 Uname: Linux 4.4.0-178-generic x86_64 .tmp.unity_support_test.1: ApportVersion: 2.20.1-0ubuntu2.23 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Mon May 11 18:41:34 2020 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: bbswitch, 0.8, 4.4.0-178-generic, x86_64: installed virtualbox, 5.1.38, 4.4.0-148-generic, x86_64: installed virtualbox, 5.1.38, 4.4.0-178-generic, x86_64: installed virtualbox, 5.1.38, 4.4.0-98-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: NVIDIA Corporation GT216M [GeForce GT 240M] [10de:0a34] (rev a2) (prog-if 00 [VGA controller]) Subsystem: NVIDIA Corporation GT216M [GeForce GT 240M] [10de:0688] InstallationDate: Installed on 2017-09-18 (965 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: Acer Aspire Z5610 ProcEnviron: LANGUAGE=nl_BE:nl PATH=(custom, no user) LANG=nl_BE.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-178-generic root=UUID=398c17c4-3b3b-4a56-92f8-6f6a37b9eee1 ro nomodeset quiet splash vt.handoff=7 Renderer: Software SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 01/19/2010 dmi.bios.vendor: Phoenix dmi.bios.version: P01-B2L dmi.board.name: Aspire Z5610 dmi.board.vendor: Acer dmi.chassis.type: 13 dmi.chassis.vendor: Acer dmi.modalias: dmi:bvnPhoenix:bvrP01-B2L:bd01/19/2010:svnAcer:pnAspireZ5610:pvr:rvnAcer:rnAspireZ5610:rvr:cvnAcer:ct13:cvr: dmi.product.name: Aspire Z5610 dmi.sys.vendor: Acer version.compiz: compiz 1:0.9.12.3+16.04.20180221-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.91-2~16.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 18.0.5-0ubuntu0~16.04.1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 18.0.5-0ubuntu0~16.04.1 version.xserver-xorg-core: xserver-xorg-core 2:1.18.4-0ubuntu0.8 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.1-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1.2 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-1build2 xserver.bootTime: Mon May 11 18:16:46 2020 xserver.configfile: default xserver.logfile: /var/log/Xorg.0.log xserver.outputs: xserver.version: 2:1.18.4-0ubuntu0.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1878050/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
