to send us more information about the machine. Please also try these potential workarounds and let us know which one(s) work: (a) Edit /etc/gdm3/custom.conf and uncomment the line: #WaylandEnable=false and reboot. (b) Disable integrated graphics/GPU in your BIOS (c) Add 'nomodeset' to your kernel cmdline in /etc/default/grub and then run: sudo update-initramfs and reboot. ** Package changed: xorg (Ubuntu) => gdm3 (Ubuntu) ** Changed in: gdm3 (Ubuntu) Status: New => Incomplete ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1821426 Title: Ubuntu 19.14 disco will not boot on Dell Precision5530 Status in gdm3 package in Ubuntu: Incomplete Status in gnome-shell package in Ubuntu: Incomplete Bug description: I'm uncertain which package is causing the problem, though I strongly suspect it may be nvidia related. This laptop runs 18.10 just fine, but attempting to boot 19.04 from a USB disk (tried multiple USB boot disks) results in a blank screen after Grub. The video will go between black with back light and black without back light. I cannot switch to a TTY, I cannot get further, keyboard seems to respond (lights up when keys are pressed). Additionally, when trying to upgrade from 18.10 the same result happens. After running the upgrade and rebooting, I cannot get it to boot unless I first start in recovery mode from grub. After that I can get to the desktop (nouveau driver seems to be installed by default). Any attempt to boot normally results in a black screen. Attempting to switch to proprietary nvidia driver results in never getting the luks screen (encrypted disk). I get no luks screen when booting normally either. lspci 00:00.0 Host bridge: Intel Corporation 8th Gen Core Processor Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Device 3e9b 00:04.0 Signal processing controller: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal Subsystem (rev 07) 00:08.0 System peripheral: Intel Corporation Xeon E3-1200 v5/v6 / E3-1500 v5 / 6th/7th Gen Core Processor Gaussian Mixture Model 00:12.0 Signal processing controller: Intel Corporation Cannon Lake PCH Thermal Controller (rev 10) 00:14.0 USB controller: Intel Corporation Cannon Lake PCH USB 3.1 xHCI Host Controller (rev 10) 00:14.2 RAM memory: Intel Corporation Cannon Lake PCH Shared SRAM (rev 10) 00:15.0 Serial bus controller [0c80]: Intel Corporation Device a368 (rev 10) 00:15.1 Serial bus controller [0c80]: Intel Corporation Device a369 (rev 10) 00:16.0 Communication controller: Intel Corporation Cannon Lake PCH HECI Controller (rev 10) 00:17.0 SATA controller: Intel Corporation Device a353 (rev 10) 00:1b.0 PCI bridge: Intel Corporation Device a340 (rev f0) 00:1c.0 PCI bridge: Intel Corporation Device a338 (rev f0) 00:1c.4 PCI bridge: Intel Corporation Device a33c (rev f0) 00:1d.0 PCI bridge: Intel Corporation Cannon Lake PCH PCI Express Root Port 9 (rev f0) 00:1f.0 ISA bridge: Intel Corporation Device a30e (rev 10) 00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10) 00:1f.4 SMBus: Intel Corporation Cannon Lake PCH SMBus Controller (rev 10) 00:1f.5 Serial bus controller [0c80]: Intel Corporation Cannon Lake PCH SPI Controller (rev 10) 01:00.0 3D controller: NVIDIA Corporation GP107GLM [Quadro P1000 Mobile] (rev a1) 3b:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29) 3c:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
