Hello,

Hello to you as well.

I really need to switch back to VT mode, because my linux does not currently work very well and I need to switch back to the console (tty1) to see the current state of the linux startup, so I now use the VESA driver, with vga=0x317 on the linux command line.

But, I only get 1024x768, not 1366x768 as with the radeon driver. Is there a vesa mode for 1366x768 ?

VESA mode should only go up to 1024x768. It's called a generic driver for a reason.

In graphic mode, the driver seems to work well so far, but the problem is that switching to text mode does not work : screen is merely black, without any text.

Your card is an R700 card, so if you want 2D accel, you need the radeon drm kernel module built on your computer. EXA fails for some reason, so it falls back to shadowfb, which _may_ be the source of your problems. Try putting: Option "AccelMethod" "none" in the Device section of your xorg.conf (under radeonhd), and see if that helps. You won't get 2D accel though.

Why are you loading 4 (ati is a wrapper for a few drivers including radeon) video drivers for xorg? I don't see any problems, judging from your Xorg.0.log (radeonhd takes over as the main driver), but you may have potential clashes there. Please comment out the sections in your xorg.conf that you don't need (i.e. everything except radeonhd).

I have no access to that laptop at the moment, so I can only reply to this : actually there was no xorg.conf file, so it is the default behaviour of the X server. Now to use the 'vesa' driver I have installed one.

Ah - the automatic configuration of the X server. If that's the case, you will need to create a new xorg.conf to force some settings for X, since the default settings aren't working so well for you. Just put: Section "Device" Driver "radeonhd" Option "AccelMethod" "none" EndSection into the new xorg.conf, and try starting X again.

That does not solve the VT switch problem :(

I don't think I can help any further - this is beyond my knowledge. :( I have had similar problems in the past as well (starting X from text mode in Slackware and quitting back) - but I was luckier than you: sometimes it would quit correctly and give me the console, but it varied a lot basically. It might be something to do with X not clearing the graphics buffer properly upon quitting, but this is pure guessing on my part. As a workaround, you could configure openSUSE to boot directly into text mode: it would involve adding a new boot entry to GRUB with the default settings, but with a runlevel appended to the end of the "kernel" entry in menu.lst (you'll need to check /etc/inittab for the text mode runlevel - it changes depending on the distro).
