Previously I was using Ubuntu 12.04.2 LTS as dom0. Although I did not get error code 43 for Intel HD Graphics 4600 in device manager, I am still getting only 16 colors on the display. I really do not know where the problem lies. Device manager says "This device is working properly.", yet I am still getting only 16 colors on the display. Could you share with me your /etc/grub.d/40_custom GRUB2 contents? Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)
