Adjust screen resolution Acer Aspire 5736z

[Ibrahim717]

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

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

sudo lshw -C display

The output should look similar to this:

sudo lshw -C display

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....

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 :

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)

Another issue that I'm having is that when my computer hibernates it goes to black screen and i cant get it to come back on with out running the "setpci" command or restarting my laptop....

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:

sudo chmod +x /etc/pm/sleep.d/99_fixbacklight

Contents of file:

#!/bin/sh


# workaround for backlight issue
