widescreen resolutions: 1680x1050

widescreen resolutions: 1680x1050

[-- Attachment #1.1: Type: text/plain, Size: 399 bytes --]

Hello,

Sorry if the post is off-topic, but the qemu users forum has been down for
several days.

Is it possible to use a wide screen resolution of 1680x1050 with kvm? the
guest OS is windows XP. I'm using the qemu parameter -std-vga, and I can use
resolutions up to 1600x1200, but the 1680x1050 is missing.

Please respond to me directly as I'm not subscribed to the mailing list.

Thanks
Francesc

The vmware VGA display supports multiple resolutions, and is supported 
in qemu, but I haven't tested it under kvm.

Thanks avi.

I couldn't manage to get it working, but I got a bit further disabling kvm
support in qemu.

These are the steps I followed, just in case somebody else wants to try:

kvm53 makes windows XP crash with the -vmwarevga parameter. I get a black
screen followed by a blue screen with an error. Something about an infinite
loop in the "framebuf" driver.

However, windows runs normally when using the kvn53 version of qemu without
kvm support and the -vmwarevga parameter.

Windows XP didn't recognize the vmware VGA driver and it's using it as a
standard vga device (which doesn't support wide screen resolutions).

I then tried to install the windows drivers for the vmware SVGA II device.

VMware provides this driver free of charge as discussed here:
http://ubuntuforums.org/archive/index.php/t-84275.html

So, I downloaded the windows.iso file from here:
http://www.vmware.com/support/esx2/doc/esx2-16515update.html

The setup program won't run since it doesn't detect vmware, but the driver
can be installed like this:

>From the windows xp guest OS, go to the control panel, system, hardware,
device manager, select the vga driver and click the install new driver
button.

Then windows finds the drivers for the VMWare SVGA II device, and hungs,
with the generic message: "a problem has been detected and windows has been
shut down to prevent damage to your computer"

Francesc

Hi,

 

If you have time you can compile a vgabios with vbe extension that support your resolution. Even though this resolution is not defined in the spec, the XP driver doesn't care. I did it for 1280x800 and it seems that it should work also for your case. The really nasty thing here is that you have to download the vgabios-0.6a package and compile it using a 16bit compiler (bcc).

 

1. First see if you can produce correct BIOS file:

Compile the source and copy the "VGABIOS-lgpl-latest.bin" to the qemu pcbios directory (probably /usr/local/share/qemu) as "vgabios.bin" and check that the KVM VM works (std-vga).

 

2. Then add a new (fake) mode to the vbetables.h file for your target resolution. I just copy and pasted an entry with similar resolution and changed the Xresolution,YResolution and gave it a unique mode ID (first value, I used 0x185, but any mode higher than the values used should be OK).

 

3. make and copy the bios again. 

 

4. Check and report back to the list ;)

 

BTW, this method is hacky. The "correct" way is not to modify vbetables.h because it is a generated file, but to change it source. I didn't have the time for it. If you do it, I will be glad if you can post it.

 

Anyhow, if you tried it, tell me what happened.

 

Shahar

Hi Shahar,

I'd like to try that.

The documentation of vgabios is not very specific about the tools needed to
compile it, but it makes a reference to a Turbo C 2.0, so i guess that's the
bcc 16bit compiler you mention in your email.

Would it work with one of the recent versions of borland's turbo C ? or I
need to find an ancient version of it?

AFAIK Turbo C is still DOS/Windos only (I haven't used it since many many
years ago). An then, I need to have an environment with both bcc and gcc..
I'll need cygwin then, which means a recent version of windows. And an
ancient DOS compiler. Nasty indeed.

I use bcc from dev86-0.16.17 (fedora rpm). You can compile it from the source. There are some problems using it on 64 bit platforms. I use a 32bit fedora VM to build such binaries.
