hey guys
i just installed ubuntu 9.04 for the first time and this is my first time with linux. i notice my resolution is stuck and i cant change it. i already tried the hardrive intaller but it gives me an error saying "System error: Failed to lock /var/cache/apt/archives/lock." When i previously ran ubuntu from the cd i was able to install it. but the resolution wouldnt let me change it higher than 800x600 either. So i know thats not the problem.
I dont know the command line stuff is there a way you guys can help me? Different ideas would help coz im kinda stupid with linux still. My laptops details are below. Thanks guys.
PS. ali this is very good site for newbies. i read all the chapters and you really made everything clear. Thanks for a great site.
Acer Aspire 4520
AMD Athlon 64x2 Dual Core (1.8Ghz)
384mb Nvidia Geforce 7000M Graphics card
1 Gb DDR2 Ram
i still have vista installed and about 8GB for ubuntu. dont have much space on harddrive. i hope this is clear enough.

Hey Sticky6,
Thanks for your kind comments about the site.
I reckon your graphics card should work just fine on your system, so maybe it's the monitor setup which is causing a problem. If you are using the laptop's LCD screen then please let me know a few extra things and I'll see what I can do to help.
Firstly, if you click on System > Preferences > Screen Resolution what is the name of the identified monitor. It may simply just be 'Unknown'. Can you also confirm that the maxium resolution you can see there is 800x600.
If the screen name is Unknown or the maximum resolution there is 800x600, please can you open a Terminal (Applications > Accessories > Terminal) and type in xrandr then press the return key. You should see lots of info about the available resolutions your screen can do. Please can you copy and paste that response back into your reply and that should definitely be able to tell me more about your screen setup.
As you have an Nvidia card, it's probably recommended that you use the Nvidia driver for your graphics system System > Administration > Hardware Drivers and clicking on the recommended Nvidia driver. This will enable you to get the most out of your graphics card. If that is what is causing the /var/cache problem, that's a bit weird. How much free disk space is on your system? 8gb is fairly small, but should be OK. Make sure you aren't already updating your system or installing some software (eg you have synaptic or add/remove software open), as that may cause that /var/cache problem also. If you still get it, please post all details surrounding what you are doing so I can help you some more.
Thanks,
Ali.
