Can I install 32 bit Ubuntu 8.04 on a 64 bit T61 or does it have to be the 64 bit version?

Thanks

No, it does not have to be 64-bit. 32bit runs.

Actually it depends on the amount of RAM. If you have 4GB+ then 64bit is the way to go. If you have under 4GB then 32bit should work just fine.

Well, actually as far as I can tell you can install both 32bit and 64bit versions on a machine with 64bit CPU. And it doesn't even depend on how much RAM you have cause linux kernel with Physical Address Extension supports up to 64GB or ram regardless of your CPU.

Additionally it might be easier to run 32bit version as you may run into problems with some software that's not in 64bit version and you want/need to run it.

Please correct me if I'm wrong.

You're absolutely correct. For this reason alone I would suggest the 332bit version to all but power users that have Linux experience.

Cheers...

Hi guys,
I took everyone's advice and installed Ubuntu 32 bit. Only thing is though, I can't seem to get the suspend/hibernate feature working. I have been searching all over the net to try and get this to work but can't seem to find the answers to it. Any of you face this either?

Thanks

This is a known issue that varies depending on your hardware config. I'm on my BlackBerry at the moment, hence I can't look it up for you. But I would encourage you to do a meta search with
dogpile.com as I believe that is how I found the fix for Ubuntu v7.10

Then a few months later v8.04 was released. I wiped the drive & did a clean install of 8.04.01, this is the first rev I've installed that has worked perfectly without further mods after the install. In fact I installed it on all four of my different 60 series models, X,T,R,Z, all ran perfectly.

I'll take a look at that. I had to modify quite a few things with this.
Middle scroll button
video drivers to have the 3d accelerator
suspend/hibernate (still gotta do this today)
That's pretty much it. Everything pretty much was working out the box cept for those few very minor issues. I think for the normal user, they wouldn't care but I think I have OCD:)

Just wanna let you all know that I got Suspend to work but when I resume from hibernate, it basically restarts the computer then it crashes. I have to power cycle the machine to get working normally.

make sure you've specified the swap partition in the kernel boot parameters.

check your /boot/grub/menu.lst

the kernel params should have something like resume=/dev/sda5 on there. make sure that's pointing to the right partition.

I'll check that in a bit. Do you think that could possibly be a cause of the laptop crashing when trying to resume from hibernation?

yes. i wouldn't have posted it otherwise.
the kernel needs to know where to find the hibernation data. without it, it'll sit and wait like it's hung.

Thanks again. I'm gonna try this soon and post my results. For me this is a very important feature than the VPN I've been trying to get working for the past week:)

It show's this:

## e.g. defoptions=vga=791 resume=/dev/hda5

I just looked in Gparted and looks like it shows my Linux partition to be /dev/sda5

Should i edit that one file and point it to sda5?

gongo2k1 · #15 Post by **gongo2k1** » Mon Aug 18, 2008 1:45 pm

the line below that should be

Code: Select all

#defoptions=

add it to that line (with the single comment), then save and run

Code: Select all

$ sudo update-grub

to make the changes. it'll be effective after the next reboot.

Do I still also edit the line that shows resume=/dev/hda5 to sda5?
