Running Mint 11 on Acer Aspire 5734Z w/ Intel GMA 4500m # Switch the backlight on after woke up from sleepīy doing so, you will be able to use the driver Intel AND a high resolution. #LIST OF GAMES TESTED ON INTEL GMA 4500MHD WINDOWS INSTALL#Originally when trying to install Mint from a live CD I was getting a blacked out screen. The video was there, but I could barely see it. I used “nomodeset” in grub, installed the OS and ended up with the same issue as described above, brightness level was right and video was visible but resolution was distorted and stuck at 1024x768. Changing the grub.cfg to acpi_osi=Linux (as mentioned above ~thank you!) instead of “nomodeset” fixed my resolution and gave me control of my brightness levels, but every reboot required adjusting the brightness level. I found this fix for the brightness level reboot issue. When I added the line of script to the /etc/rc.local file as suggested and rebooted my system there was no need to adjust my brightness settings. It worked! :) Or it worked until my system went into screensaver/standby mode! Coming out of standby I still had to manually adjust my brightness settings.
