I've just ordered myself a new Cosmos VII laptop from PcSpecialist. I've done a number of Ubuntu installs in the past, and generally speaking they Just Work. Alas, not this time. The machine is an I7 CPU with the NVidia GTX 1050 graphics card, and no other OS. * The first problem was that booting from the USB startup disk hangs while either trying to "Try Ubuntu" or "Install Ubuntu". Googling suggests that this is due to graphics driver issues, and to add "nomodeset" to the grub boot command. This does indeed stop it hanging, but: * the second problem is that with nomodeset on grub, the aspect ratio of the installer is out-of-whack, and some of the dialog boxes are off screen. It's kind-of OK because I can tab to the "ok" button to proceed through the installation, even when it's off screen, but then: * having completed the installer, and booted to the Ubuntu login menu, when I log in I get the "black screen of death" - a mouse pointer, but then everything freezes up. Again, googling suggests maybe graphics driver issues, but the suggested work around is to install the nvidia drivers and I can't get a console up with ctl-alt-F2, even from the boot screen * I also can't get the Grub boot menu to appear. The suggested route, hitting shift after the BIOS boot, doens't work. Hitting ESC *does* get the grub command line interface, but I'm not sure what I need to do from there to get a text-mode boot. I haven't yet tried: disabling BIOS options, like secure boot, or installing an older Ubuntu distro. I also feel that there are more intelligent grub options I can other than just 'nomodeset' (I don't really understand what that does, I just copied it from a forum posting I found!), but I've reached the limit of my understanding of the lower levels of Ubuntu. Very happy to receive any suggestions! Thanks, Ian
Maybe try getting into "safe-mode"? https://askubuntu.com/questions/172319/how-can-i-start-ubuntu-in-safe-mode -- The Mailing List for the Devon & Cornwall LUG https://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
