Greetings. I'd like to ask if it's planned to implement l4con's --vbemode command line option in l4dope too? I couldn't get grub's vbeset option to work in QEMU (always ends up in black screen), but l4con-s vbemode option does work. -- Gábor Bérczi
Hello,
I'd like to ask if it's planned to implement l4con's --vbemode command line option in l4dope too? I couldn't get grub's vbeset
We do not plan to implement this feature for DOpE but technically, there is no argument against it. So please feel encouraged to try porting this feature to DOpE ;-)
option to work in QEMU (always ends up in black screen), but l4con-s vbemode option does work.
I wonder what goes wrong with setting the VBE mode with GRUB? Are you sure, you use the proper GRUB version? The standard version of GRUB does not support vbeset. You can find Adam's patches for GRUB versions with vbeset support here: http://os.inf.tu-dresden.de/~adam/projects.shtml Regards Norman

I use 0.97-os.1, took it from the demo CD AFAIR. The CVS version is quite uncompilable, but if there is interest I can submit the bugs here. This is the last message (on serial), while the Qemu screen is black and empty (it does change its size, so I guess vbeset works, and the failure is in L4/Fiasco somewhere) Welcome to Fiasco(ia32)!

That is a very untypical last message and tells me quite nothing about your problem. However, I have compiled an ISO image for you, which features current binaries, uses GRUB's vbeset, and works with QEMU. You can get it here: http://os.inf.tu-dresden.de/~nf2/tmp/vbeset-image.iso You should try out this image using the following command line options to see all debug messages: qemu -m 64 -serial stdio -cdrom vbeset-image.iso If this works, compare your menu.lst file against the one on the ISO image. You could also try to successively replace the binaries on the ISO image with your binaries or vice versa. Good luck! Norman

Yes I thought so.

Thanks. Doesn't work ;( The effect is the same. I've tried Q.app version Q-0.8.1a35 and Q-0.8.2d52 with OpenGL, DirectDraw, and Quartz video outputs, with or without the Q frontend. /Applications/Q.app/Contents/MacOS/i386-softmmu.app/Contents/MacOS/ i386-softmmu -cdrom vbeset-image.iso -boot d -serial stdio -m 64 -- Gábor Bérczi

Works fine here. I am using Q version 0.8.2d52 with OpenGL on a MacBook Pro running OS X 10.4.8. Trying to find the difference: Are you on a PowerPC or an Intel Mac? Michael PS and OT: Are you the Gabucino who worked on MPlayer? I am asking because I am the Michael from xine. :)

Mine is a PowerPC model. I'll check it on an intel one.

:) Yes it's me. Good old (flaming) times before YAML (yet-another- mplayer-leaving), huh? :)) At least I found it to be of great fun... [OT] -- Gábor Bérczi

Ok I tested it. Using the same harddisk image: - on a MacBook, and i386-softmmu (i386), l4dope works!! - on a MacBook, and i386-softmmu (ppc - rosetta), it segfaults before grub screen - on an iBook, and i386-softmmu (ppc), l4dope doesn't work, as I said So it would seem that the i386-softmmu/ppc binary is broken somehow. I'll compile my own tonight and see if it makes any difference. -- Gábor Bérczi

Sounds like this is a job for the Q/qemu experts. <OT>

In the end it was quite fortunate to have these two competing projects. Linux multimedia wouldn't be where it is now without the fighting. Unfortunately, both projects have lost pace. :( </OT> Michael

BTW when I press a key on the empty screen the box reboots, so this is a Fiasco kernel panic. Can't get it onto the serial console for some reason :( -- Gábor Bérczi
