I installed linux mint 13 two days ago.
i have acer aspire 5750G with 4Gb ram, i5 second gen, 1GB nvidia graphic card and dual boot win and linux.
I had two major problems:
1)The brightness control doesn't work by default so, i added GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor quiet splash " on to file /etc/default/grub.
2)The nvidia card heats up a lot taking the battery life from 3 hrs 45 min to 1hr 10min. so, the solution i found was:
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
running these three lines on startup stops the heating improving the battery life to 3hrs 30 min. i made a script and added it to /etc/rc.local file.
I informed about the above problems because i have made the changes to boot.
The current problem is every time i boot into linux mint it just freezes completely as soon as desktop appears. I hold power button to turn off. Initially two or three time it used to boot but now its not (it used to boot even after the changes were made).
i am not very good at linux so please bare with me and i forgot to inform i used to use ubuntu12.04 before i installed mint.
