    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hi MAFoElffen

    so I tried your xorg.conf file, placing it in the /etc/X11/ directory. unfortunately it didnt work out. problem appears to be even worse now. cannot start ubuntu, even with the "recovery boot -> resume boot -> manual shutdown -> manual restart" trick. deleted the file using the Ubuntu live usb, but problem persists.

    ...
    any other idea?

    You may try to start with safe graphics mode and restore your current xorg configuration or reconfigure. I had this problem with my onboard graphics, but when insert back my nVidia graphics card back, all worked.

    All you did was add the xorg.conf file right? Getting rid of it should have got you back to where you were before... That was the only change. Pull the battery to ensure nothing is hanging around resident.

    I simplified and cut them down. Try one of these.

    Honestly, I don't know if this will help you or not.
    I had lots of boot / black screen / lockup problems with my HP laptop and Ubuntu 12.10
    Finally got it sorted out.

    I do not have a file: /etc/X11/xorg.conf and I am running fine.
    If you have Intel graphics, that seems to be a big problem with laptops.
    I am using boot arguments: "nomodereset nosplash i915.blacklist=1"

    Good luck. You can fix the problem.

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Yes... Usually Intel chipsets are not a problem. Sometimes with older laptops, then some 915 issues. A couple years ago, they introduced the Sandybridge CPU w/ an Intel APU, then there was issues again on those early chips. But usually... and more often on the laptops than on onboard desktop mobo's. On intel, since intel does opensource and shares their code with Xorg, if there is an Intel GPU, then it usually defaults to that driver with little problems.

    But heck.... have to still get you going somehow. Anyway of sharing an /var/log/Xorg.o.log on it?

    Hi!, ozz1234,

    Welcome to the Forum.

    Sounds like you had a monitor screen backlighting problem.

    If it is still "sorted out" after rebooting, please confirm you do not need anything more.

    Chao!, bogan.

    Re: Graphics Resolution- Upgrade /Blank Screen. easy way to fix

    Hold a light (flashlight or such) at an angle to the screen to see if it is displaying, but not backlit...

    If so, then try hitting <Fn><Down-Arrow> or <Fn><Up-Arrow> a few times to see if it alters the brightness setting at all. Sometimes the brightness setting is reversed on some devices, so it come up as dark, then needs the <Fn><Down-Arrow> to get brighter... even though that hot-key combo is usually to get darker (reversed meaning). One of mine is like this.

    On some devices without a <Fn> key (like some Dells), the key-code gets sent for that by holding down the left <Cntrl><Alt> keys. So then the combo would be <Left-Cntrl><Left-Alt><Down-Arrow>...

    The video driver is currently under System Settings > System > Software Sources ... last tab is Additional Drivers. But changing that should not affect that subsystem.
