Ubuntu: HP Pavilion 15 with AMD dual graphics - Ubuntu live environment not starting


I've had this laptop for about a day now and have decided to try Ubuntu on it and determine if I want to install it. I created a USB, it booted (Secure Boot was on, I tried with Secure Boot off to no effect), and then the problem occurred.

The screen turned off for a second, turned back on to a black screen, shut off again and turned back on with a dialogue box telling me that the system had to use low-graphics mode. I clicked OK, selected low-graphics mode from the menu and clicked OK. The screen switched to the boot messages and did not go any further than this. Ctrl+Alt+DEL started rebooting the laptop though.

I tried booting again, but this time I edited the boot options in GRUB to add nomodeset. This time, the laptop only booted to a black screen. Ctrl+Alt+F2 took me to a prompt, I tried startx from there, but X didn't start, complaining that it wanted kernel mode setting back.

I can not seem to find any option to disable one graphics chip or the other in the UEFI setup menus.

Laptop : HP Pavilion 15-E004AU.

The CPU : AMD A6-4400M APU with Radeon(tm) HD Graphics

The graphics chip : AMD Radeon HD 7520G + 8670M Dual Graphics.

The Ubuntu version : 13.10, 64 bit.


EDIT: I tried 12.04.3 LTS, it managed to bring the desktop up. There are severe graphics glitches after about two minutes though.


I had similiar issue with Ubuntu 13.10 on HP Pavilion 17-e050sm laptop:

Microprocessor AMD Quad-Core A4-5000M APU with Radeon HD 8330 Graphics (1.5 GHz, 2 MB cache) Chipset AMD A76M FCH Memory 4 GB DDR3 Video Graphics AMD Radeon HD 8330 Graphics (up to 1.98 GB)

and solved it by passing nomodereset kernel option (press F6) before booting live session. Hope it helps you,



The one solution that solved this for me was trying Ubuntu 14.04's Beta 1 image, written to a USB. It booted from this image to the live environment without any issues whatsoever, and installation worked perfectly. After reboot, it booted from the HDD, then rebooted itself twice. After that, I was able to log in and use Ubuntu.


I could solving for ubuntu 14.04 in hp pavillion by installing fglrx HP Pavillion is is AMD/Intel Hybrid system, so switch to shell mode and install fglrx and fglrx-pxpress:

sudo apt-get install fglrx fglrx-pxpress
