problem resolution video after installing 5.0.3 vicibox stan

[callit]

after installing "os-install" to restart the server I have problems with the screen resolution and not see anything.
I read the guides tell me where to access from the Recovery Console and modidicare / etc/X11/xorg.conf that I find, there is only / etc/X11/xorg.conf.d / and there is nothing .
how can I solve this problem?

[DomeDan]

the short answer:
Use yast to edit the boot loader and set the flag vga=791

the long answer:
you can boot normally with the vga=791 option by pressing 'e' when you are in grub
that puts you in edit mode, select the line containing "kernel ..."
and navigate to the end of that line and just type in:
vga=791
and press 'b' to boot (not sure if its 'x' to boot in 5.0.3 maybe)

hopefully that will work.
If it does and you want to make it default, then login with root and type:
yast
In yast select "System" -> "Boot Loader"
use tab to select the one which is marked as default and tab to "edit" and write
vga=791
in the "Optional Kernel Command Line Parameter" field

791 is the 1024x768 resolution 16bit, here is a list of resolutions: http://pierre.baudu.in/other/grub.vga.modes.html

thank you very much

Hi,

Do I need to boot again from the live cd in order to do that?

During boot without cd it just says Welcome to GRUB! and then it blacks out. Pressing "e" does not do anything.

Trying to access Yast / Boot Loader with liveCD gives me error "Becase of partitioning, the boot loader cannot be installed properly"

Please help

Thanks

Sounds like you setup the partitions wrong.

here is a tip that might help you in this situation:

The installer can sometimes be finicky about hard-drives that have been repurposed from other things, I.E. non-blank drives. The easiest thing when this happens is to just wipe the partition table of the effected drives, and reboot onto the CD to start the install. DO NOT DO THIS ON A LIVE SYSTEM! It WILL flatten your drive, costing you ALL your data!
1) Boot from ViciBox cd and login as root with password vicidial
2) Type this: dd if=/dev/zero of=/dev/path bs=512 count=1024
3) Reboot from ViciBox CD and proceed with Phase-1 install

replace /dev/path with the path to your hard-drive,
if you dont know the path then you could try the command fdisk -l to figure out what hard-drive you want to use and the path to it.

What is the name of the ISO you are trying to install, and what kind of hardware is it?

[ricardochenhe]

Im trying to install ViciBox5.i686-5.0.3

The hardware is an old Dell 6650

Im pretty sure I choose to delete and recreate all partitions. I can try again with what you posted.

Yesterday I gave up and instead installed Ubuntu server on it, and it happened the same thing, at GRUB it went out of range, but I was able to access vi SSH figuring out the DHCP ip.

I'll try again in another box with your suggestions.

[DomeDan]

If you can access it using SSH then its not a partition issue, but yeah try my suggestion with vicibox.

It does not make sense that it gets black after "welcome to grub", maybe you need to use the old grub... try with an older vicibox or any other linux distrubution,
if that works then you need to install the old grub during the install instead of grub 2, not sure how but its probably possible.

but it might work if you add vga=791 or nomodeset to the kernel options even though you cant see the stuff after "welcome to grub".
to add that you need to boot a live cd and chroot into the installed system

edit:
can you change to an other tty if the system boots (even though the screen is black) try to press Ctrl-Alt-F2 to get to tty2

[ricardochenhe]

Pressing Ctrl Alt F2 did nothing.

Tried chroot, changed some GRUB varialbes, did not work...

However.... turning off the server and back on WITHOUT the screen and plug in the screen back again after grub did the trick well, i least I got video, now it appears that I have another issue of /dev/sda1 not found

[williamconley]

sounds like your video value in the boot is wrong. i've had that several times on several os's. if you can ssh in, modify /boot/grub/menu.lst and find the vga=0x314 entry. look up the possible values for this and set it to the dumbest (lowest resolution) possible.

beware of line breaks.

good idea to copy the file before changing it.

also good idea to learn to modify it while booting from a live cd (which would require mounting the drive, among other things) in case you screw it up.

if you want to play with it all at once, you can duplicate the "title" to the next "title" and make several new sections (each with a unique title) and try lots of values.

but: it should still show the video during the grub. i've never bumped into that one. you sure the video isn't just dying? (card or monitor ...)

you could also try a different monitor.

[Kumba]

Video drivers seem to cause half the problems of installing ViciBox. The other half seems to be finicky drive controllers like BIOS RAID and psuedo-RAID controllers. If neither of these two stop you then it will usually run like a champ. That's why in the instruciton I say to boot with 'text' mode from the installer prior to doing the os-install step.

[ricardochenhe]

Don't know what exactly was causing the no video issue, but unplugging the monitor before turning on the server solved the issue.

Now I have raid driver issue, which I gave up and used a newer server.
