TC resolution on Virtual Box hosted by W7
« on: September 16, 2011, 01:02:20 PM »
Hi,

I`m new here, I have been using various Linux distributions for a couple of years, so I wanted to get my hands dirty with Tiny Core.  After playing around with it, reading the manual, ect I got a good feel with it.

Just that the screen resolution sucks...

I`m running tc in Frugal mode in a Virtual Box machine hosted by W7 on a laptop with 1600x900 screen resolution.
As you know, the default resolutions don`t come close to what I have.

I have tried several work arounds by messing with the settings, installing Xorg-7.4, Xorg-7.5, followed the suggestions done in this topic: http://forum.tinycorelinux.net/index.php?topic=6495.0
tips from this page didn`t work either: h t t p : / / [removed due to policy violation]/os/tutorials/tiny-core/resolution.html
nor the suggestions of the xvesa vs xorg articel on the TC wiki.

Either I don`t see any changes, or either I`m stuck in console mode and startx dies or doesn`t do anything...

After looking for a week I`m getting desperate for some help...

Thanks for anybody who can provide any hints or help.

Hi fristi
If you tell us what kind of graphics chip you are using, someone who is familiar with it might be able
to help. Also, maybe you could be more specific about

Sounds like a Virtual Box problem to me.
TC can only use the virtual resources provided by the virtual machine.
Have you tried a Virtual Box forum?

Hi,

thanks for the fast reply :)


at Rich:

I have a switchable graphics card:  AMD 6630M or the intel HD3000

with the work arounds I ment the links I provided:

- installing Xorg-7.5 running in configless mode makes my xtart do nothing
- installing Xorg-7.4 and the graphics tinycore extention running configless makes my xtarts do nonthing
- creating an  xorg.conf file with content below makes my startx crash:

Section "Monitor"
 Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Option          "AccelMethod" "UXA"
EndSection


crahs errs are:
signal 11, fatal IO err 104 on X server ":0.0"


- running "Xorg -configure"  and then startx gives empty black screen

I think those are the things worth mentioning



at Gerald_clark:

I havent tried VirtualBox forums yet,  I will install a fully loaded Linux distro to see if I get that one running on the correct resolution. If not, they it might be virtual box, might be a shot

Generally speaking you'll need to install the 'virtualbox-ose-additions.tcz' extension in the TC VM if you want to use any "non-trivial" resolution.

If you carefully read (and apply) the info for that extension you should end up with at X server where the resolution can be adjusted by e.g. re-sizing the window on the host.

A much more limited set of options exists if you stay with the default 'Xvesa' X server. On my newest notebook (with a 1920x1080 resolution) I can run Xvesa -listmodes 2>&1 | sort -k 2n and it shows '1600x1200x24' as the highest resolution. If I would use this one (by changing the respective string in the '~/.xsession' file, or using a 'xvesa=1600x1200x24' boot code) I'd end up with horizontal and vertical scrollbars in the host window (which is not a particular useful situation). I can choose any of the other resolutions, but they are mostly limited to 4:3 or 5:4 ratios (with '1152x864' or '1280x1024' being the largest ones still fitting into my host screen), which is probably of limited value when using a widescreen notebook.

Hi Maro,

thank you for the info.  As soon as possible when I get good internet access I will try your tips.
Currently I have very limited access.

Thanks again, I`ll keep you informed!
