I am new to Linux/Ubuntu. I have a HP Pavilion 20 Desktop and have just installed Ubuntu 16.04.2 from a flash drive.
Processor: AMD E1-1200 APU with Radeon(tm) HD Graphics x 2, Graphics: Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)
The screen goes black when I boot up. I am able to get it working by going to the GRUB menu and typing "nomodeset" I tried updating my graphics card driver but no update was available. Could use some help.
This answer from Coldfish fixed the problem.
You should add this option to /etc/default/grub, firstly:
sudo nano /etc/default/grub
and then add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
GRUB_CMDLINE_LINUX=""
And then save by hitting Ctrl+O, then exit nano with Ctrl+X, then simply run:
sudo update-grub
nomodeset to GRUB_CMDLINE_LINUX_DEFAULT allows the Ubuntu GUI to boot on-screen, but the graphics options are extremely limited (only 800x600 is available as a resolution). When booting without nomodeset, if I hit CTRL+ALT+F1 during boot, something occurs and Ubuntu boots normally, and the resolution is correctly set at a 16:9 resolution. Any ideas why?
