[ SOLVED ] Display stuck @640 x 480 following LL installation: how do I fix it?

[TheDead]

Thanks!
I'll check but what I meant by "locked" is more about the chipset's architecture itselft only supporting 2GB and not physically having the pipelines for more.
I know my old Atom netbook was stuck at 2GB (confirmed by research).

Sorry for zhe confusion.

Grats on the solve!
I see that you have a D630... can I ask how much memory you have in that machine? I was never to put more than 2GB :-(, think it's hardware locked I read somewhere, so just checking.

Yes, TC is a mine of info; so good to have people like this around; also if noone else gives me an answer TC usually does 
The 640x480 issue was on a fresh install on a laptop someone gave me for free (Packard-Bell MX37) earlier this week. LL3.8 64-bit runs on it brilliantly.

Turning to the Dell: when I bought it 2nd-hand in 2016 (from Amazon) it came with 4GB pre-installed, which is overkill for my needs; 2GB would have been ample. Just now I contacted Crucial.com re. RAM: they told me that with this Dell model the max you can install is 8GB.

Hardware locked? I don't know anything about hardware-locked PCs, but if RAM's expandable, can't you unlock it (though I don't know anything about this)?

Hit c at your grub screen to get a CLI.

yep, done

Type videoinfo at the prompt and check that your preferred mode is the correct resolution.

Yep, the preferred res. of 1024x768 is listed (but doesn't appear in Display Settings GUI, yet)

If not then boot and uncomment GFX mode in your default grub and type in the correct resolution and update grub.

It did list my preferred resolution, but I still opened the grubfile following boot-up and uncommented GFX mode & replaced 640x480 with 1024x768 & then updated grub (sudo update-grub).

Result=Success
On booting, 1024x768 resolution working, and is listed in Display Settings GUI - rather surprised to see the refresh rate is given as 76Hz (used to seeing it usually around 60) - oh well, even better !
Home & Dry!


Many thanks TC, much appreciated

If not then boot and uncomment GFX mode in your default grub and type in the correct resolution and update grub. This will not work unless the resolution is listed in the videoinfo list you just looked at but will if it is there.

maybe forcing VESA to 1024x768 or something in some way would be better.

Already done - see code in reply #1 above.
I'm not sure I'd go along with some of your suggestions, but you made me laugh out loud !
You've got a good sense of humour, something that's always needed in good measure ...

I think there was another thred in the forum about this graphics chipset (SiS) and that support stopped quite a few kernels ago.
I thing I also mentionned the same in that older thread but when I see SiS, I usually run away, like in Monty Python... "Run away...."

But, maybe a usefull tip, you could maybe use ndiswrapper (command line version, no GUI) and install a Windows driver for it... and pray.
I would also Rub Buddha's Belly for luck, throw coins in a fountain, get a horse shoe necklace and try to find a four leaf clover....
Don't expect miracles though, maybe forcing VESA to 1024x768 or something in some way would be better.

A few hours later: just worked out why I couldn't boot from the LL installation DVD on the Packard-Bell laptop: it wasn't enough to just select CD/DVD from the Boot settings, but I had to 'physically' move it to the top of the boot-order list, using the '+' character key. So I reinstalled LL 3.8 (this time 64-bit) and everything went very well.

But: I still have a display resolution problem. During the LL installation process, the screen resolution appeared normal, but on reboot following installation, the resolution is stuck (once more) at 640 x 480 with no other choices apparent in the Display settings, as shown in the screenshot in post #1 above, and in terminal output here:

changing this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"to either

Got given an old laptop today for free, i.e. a Packard-Bell Easynote MX-37 (dual-core CPU @1.47GHz, 2GB RAM)
First thing I did was remove HDD (Vista installed), replaced with an SSD.

LL3.8 (32-bit) wouldn't install onto the SSD, using conventional methods: tried both USB pendrive & DVD installation methods, selecting boot order from PC Settings. Both failed (even though found later that USB & DVD drives do work)

So, I installed LL3.8 onto the SSD using another machine, but without doing the updates on that machine. Then took SSD out of this machine & installed back into the Packard-Bell, rebooted and voila! It worked, BUT ...  the screen resolution is stuck on 640 x 480 resolution with no other choices available from the Display Settings - as you can see from the screenshots this resolution is too large:

I then ran 'Install Updates', but this did not resolve the issue 

Any ideas folks, on how to resolve this ?
