    Question Adjust screen resolution Acer Aspire 5736z

    Hello all.....

    I am new to Ubuntu and linux for that matter and I am attempting to learn to program and making the switch at the same time.... Thus I would be considered a beginner. The reason I am running 13.04 is because 12.10 gave me so many problems which no one could answer that I began to try new versons of Ubuntu and 13.04 has been the by far the best i.e. touchpad works ... I have been able to get the wifi to work and i dont have a black screen when booting up or after updating.... These things are essential or me making the switch to linux due to the fact that, I fully commited to Ubuntu and erased windows 7....... Anyways thats just a little backround info and why I will be probally asking question that someone who is testing the daily build should know already and why if you chose to provide support please dont assume that I know what you are talking about....With that said


    How do I change the screen resolution... When I go to system settings --display ---- it only has one setting " Laptop" is there a way to put more settings "i.e. code into the termanal that will allow me to create a sharper image .... and utilize the high res of my monitor....

    Thanks in advance

    Re: Adjust screen resolution Acer Aspire 5736z

    Changing screen resolution, depends on what graphics driver you are using. Could you paste the output of the following command in you next post:

    Code:
    sudo lshw -C display
    The output should look similar to this:

    Code:
    sudo lshw -C display

    Re: Adjust screen resolution Acer Aspire 5736z

    OK, Talk about diving into Ubuntu this issue has taught me a lot and I'm only half way to resolving it... good this is I think i have learned how to communicate in a way where I am help able.

    The issue was that i was using the default Intel driver because in order to install 13.04 I had to press f6 and select nomodeset..... in order to see what I was doing....

    To get back to using my Intel GMA 4500M I took out nomodeset and added acpi_osi= to the grub .... this has given me the resolution options that I want.... However now My back light goes off if I change resolution or upon reboot. so each time I have to run this command in the terminal on a black screen "sudo setpci -s 00:02.0 F4.B=00".......


    So no I need to know how to get the setpci script to run automatically at boot and during every other instance when its needed.....
    here are the links I used to deal with this issue....

    Re: Adjust screen resolution Acer Aspire 5736z

    Here is a possible solution that I found in one of the links posted earlier.... I want to try this but have no Idea how to perform those tasks.... i.e. add setpci to file or make a new executable file.... can someone give a step by step or post a link or two.....

    "I run this command under no-backlight condition on terminal (I still can read my screen under flashlight):
    sudo setpci -s 00:02.0 F4.B=00
    and my back light is back!
    but back light is off again after reboot, need to run that command again
    All I did was add the setpci command into sudoers file (sudo visudo) so i don't need to type password when running setpci,
    and make a new executable file contains that command, then make new startup entry to run that executable file every startup.
    Now i have my back light function normally every startup..
    Try this guys, who knows it can help you."

    Did You try putting it in /etc/rc.local which runs with elevated privileges...?

    I was going to ask how to do this but though to myself I better figure that out on my own.....

    so by typing into the terminal : gksu gedit /etc/rc.local
    I was able to put:

    sudo setpci -s 00:02.0 F4.B=00 into the file

    my rc.local now looks like this :

    Code:
    The following command has solved my problem. To make it run after reboot
    just insert the command in /etc/rc.local (by default this file is empty and
    is equivalent to windows' autoexec.bat). My rc.local looks like this:
    #!/bin/sh -e
    #
    # rc.local
    #
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will "exit 0" on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.
    sudo setpci -s 00:02.0 F4.B=00
    exit 0
    Now I can reboot with out a black screen and my resolution is nice. However when adjusting screen resolution my screen still goes black.... This is not a deal breaker for me but I would love to figure out how to fix this issue also.


    ( Horray my first big Ubuntu problem solved..I see why this stuff is addicting.... Thank YOU All who helped now and in the past)

    As I said You do not need sudo in /etc/rc.local since it is executed with elevated privileges already...

    Create a file called /etc/pm/sleep.d/99_fixbacklight and set it executable:

    Code:
    sudo chmod +x /etc/pm/sleep.d/99_fixbacklight
    Contents of file:
    Code:
    #!/bin/sh
    
    
    # workaround for backlight issue
    
    
    case "$1" in
        resume|thaw)
            setpci -s 00:02.0 F4.B=00
            ;;
    esac
