I think they are not same. In bug https://bugs.launchpad.net/bugs/1782347 the user says he needs to boot with nomodeset for both the installed and liveCD. I can boot with bootable pendrive just fine without using nomodeset.
Also the user says "GDM3 will not boot (the screen will keep on flashing in semi-textual mode, with a white mouse arrow stuck)." I on the other hand get a black screen(no mouse cursor or flashing) after selecting ubuntu from grub menu. Work-around for this is that I wait for a minute and press the power button to suspend and press any key to get to the login screen. So I think GDM3 Boots. I aslo tried your advice "Please edit your /etc/gdm3/custom.conf and comment out: WaylandEnable=false" but it didn't work and had to boot with work-around I mentioned above. Also adding nomodeset allowed me to boot without black screen, but it randomly froze the laptop forcing to do a force shutdown. So I removed nomodeset. ** Tags added: apport-collected ** Description changed: After a fresh install of ubuntu 18.04LTS(dual booted with windows 7) when I selected ubuntu from the grub menu to boot into the OS. But I got a black screen I waited for few seconds but I was still at black screen. So, I forced shutdown the laptop. Again in second attempt to login I got black screen this time I waited for more than a minute and pressed power button once which suspended the pc then I pressed enter and I was presented with login screen. To solve the problem I followed this guide https://askubuntu.com/questions/1029624/ubuntu-18-04-live-boot-leads-to- blank-screen and changed quiet splash to nomodeset quiet splash. After applying this fix there was no black screen at the time of login, but the laptop started to freeze randomly even when left idle for more than 30 mins it would freeze. I had force shutdown each time and this happened very frequently. I again changed nomodeset quiet splash to quiet splash, which again leads to black screen after selecting ubuntu from the grub menu. I also did RAM test using Memtest86 from GRUB and everything was fine systemd-analyze time Startup finished in 6.015s (kernel) + 1min 26.820s (userspace) = 1min 32.836s graphical.target reached after 1min 25.472s in userspace ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7 ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18 Uname: Linux 4.15.0-29-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Tue Jul 31 00:17:48 2018 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu DkmsStatus: virtualbox, 5.2.10, 4.15.0-29-generic, x86_64: installed ExtraDebuggingInterest: Yes GpuHangFrequency: Several times a day GpuHangReproducibility: Seems to happen randomly GpuHangStarted: Immediately after installing this version of Ubuntu GraphicsCard: Advanced Micro Devices, Inc.
