INTEL GMA 4500 TO INTEL AMD INSTALL
Originally when trying to install Mint from a live CD I was getting a blacked out screen. Running Mint 11 on Acer Aspire 5734Z w/ Intel GMA 4500m
INTEL GMA 4500 TO INTEL AMD DRIVER
# Switch the backlight on after woke up from sleepīy doing so, you will be able to use the driver Intel AND a high resolution. The problem arise when you wake up from sleep as well, so you have to create and edit the file /etc/pm/sleep.d/10_screen_sleepand copy this : #!/bin/sh You have to modify /etc/rc.local to make it permanent at startup. To switch on the screen you you have to sudo setpci -s 00:02.0 F4.B=00Įither by ssh or blindly with a tty and it magically switch on the screen. I've written the solution here it's in French but you may Google translate it.īasically, the black screen is just a side effect but the it boots well, you can see that it is working if you use a torch light and point it to the screen. The black screen is only due to the fact that for some reason, the backlight is switched off. My display works fine now, but in reverse.Īctually it works with the i915 driver and modesetting activated but there is a little trick to do. So if your display starts with a blank screen, try decreasing the brightness to check if the screen appears. nomodeset option works at reduced resolution, black screen with default graphical installer. I see no lasting benefit to having turned it on and off as described in Comment #18 - still doesn't work with it off here. Of note, kdm comes up at the correct resolution with nomodeset but once the X session starts it falls back to 1024x768.Īcpi_osi=Linux is required for the back light keys to function. With nomodeset 1024x768 is the only available resolution once logged in to a session. X won't start with kernel modesetting, either automatically or from runlevel 3.
Starting with kernel modesetting gets me a graphical console that works fine On my keyboard, brighter is Fn-left-arrow and dimmer is Fn-right-arrow, which is different than I usually see. Hitting Fn-brighter once turns it back on. Without i915.modeset=0 the backlight does appear to start in the off position. since it is reverse, max brightness = blank screen.įollowing are a few interesting notes from the link: I Googled for answers but nothing seemed to solve my problem.įinally I came across this that says for acpi_osi=Linux, the brightness meter works in reverse, which was why my display started with a blank screen i.e.
