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.

Hi Ali,

Okay i solved the problem Ali but i dont know what i did. I went to Synaptics and searched Nvidia. I downloaded a package called Nvidia-glx-180. i thought it was a driver. so i installed it and now its fixed. maybe im stupid maybe that was the driver. its also activated in the hardware drivers menu. so i guess that was it. or what?

im gona paste the info you asked coz im not sure if it will tell you what the problem was.

xrandr

stian@stian-laptop:~$ xrandr

sorry if i seem too confusing.im confusing myself here. so far linux is doing good. got my plugins for firefox and i can now watch movies too.

i just have another question if thats okay....when i use kompozer to design my web pages, it just crashes all of a sudden. im not doing anyting wrons while i edit it. when i open some menus it just closes the application. weird.

thanks again for your reply ali.

Hey Stian,

 Well done on fixing your graphics issue. Sounds like it was just the wrong driver installed. The output from xrandr there shows that your system supports resolutions of up to 1280x800 without problems. I think it's indicating that you are using 1024x768 resolution at the moment.

On the point of kompozer, i'm unsure of why you would be having that problem, but perhaps removing the config files for it may help. Here is a neat trick to delete the hidden configuration files in your home directory for Kompozer:

Applications > Accessories > Terminal

mv .kompozer .kompozer-broken

Then start up kompozer again. It should create a new configuration file. If it still fails, then try starting kompozer simply by typing the word kompozer in the terminal window and copying and pasting any error messages that it puts on the terminal screen into your reply. I tried out Kompozer here on my 9.04 setup and it seems to work fine so hopefully this will fix it for you.

Cheers,

Ali

Hi Ali,

sorry for taking so long to reply i was busy for two days trying to fix my fiance's sister's computer only to find the onboard video card has broke. Among some other...

Anyway...

I started Kompozer out in the terminal view and then i wanted to change the view. As soon as I open the view tab on the menu, kompozer crashes. This was the first error in terminal...

stian@stian-laptop:~$ kompozer
Segmentation fault

Thats it. The only fault i get. I then proceeded to regenerate the error and after it happened again, i put in the code you gave me. Only to find the same thing happening again. I posted my whole terminal output here for about 4 or 5 tries. Same error and the code doesnt make a difference.

stian@stian-laptop:~$ kompozer
Segmentation fault
stian@stian-laptop:~$ kompozer
Segmentation fault
stian@stian-laptop:~$ kompozer
Segmentation fault
stian@stian-laptop:~$ mv .kompozer .kompozer-broken
stian@stian-laptop:~$ kompozer
Segmentation fault
stian@stian-laptop:~$

Hope you have a great weekend.

Stian

Hmm, that's odd. A segmentation fault is basically a crash, but it's usually a result of when the software tries to access a place in the computer's memory it's not allowed to, so if you have any other stability problems it might be something to do with your memory being dodgy, but this is unlikely.

Can I ask how you installed Kompozer? did you install it via the normal Add/Remove Applications or Synaptic router or did you do it some other way? I have 9.04 here and Kompozer is pretty much rock solid, I installed through Synaptic (which is the same as Add/Remove Applications). If you installed by downloading a package off the net then this could explain why.

Cheers,

Ali

i installed it using the synaptic package manager. i uninstalled it a couple of times but it still does the same thing. i dont know why. i saw on forums there were alot of people having problems with this. it sucks though.
