Black screen on laptop, works only with radeon driver from Bebits

[kutspam@…]

There some weird thing with this driver and ati mobility m6 in the HP nc4010. Zeta: screen switches to black after boot icons, BeOS with same? bebits driver too, solution: remove driver, reboot, reinstall, reboot works. In zeta select Use panel = always in screen prefs and your sceen won't go black after colour depth changes.

In haiku the 'remove driver, reboot, reinstall, reboot'-method won't work, screen stays black. With radeon driver from bebits this method works but I can't set sceen resolution or colour depth (it won't change anything).

IRQ is deactivated in Haiku Radeon driver (by axeld). To have it working along an audio driver (for the same IRQ IIRC), I had to activate IRQ again.

Where / how can I activate the IRQ for VGA? I'd like to test it. If I use the radeon driver from Bebits, should the screen prefs work? Do the screen prefereces work at all? There's like I said before an issue with the panel (screen) not being activated and thus the screen stays black, who maintains the driver?

Seems that the backlight isn't always activated with the bebits radeon driver (originally by Tomas Kurschel, now maintained by Euan). Could be related, see the bebits talkback if you have time.

This bug should have been fixed already, since interrupts have been reactivated for the radeon driver.

This bug still persists, I had to put an external monitor to the vga out to get a picture to be able to set the "Use laptop panel" "Always" After that it works.

This time a installed Haiku rev 18081 over the older version but didn't replace the settings folder in /boot/home/config/settings.

radeon driver works normally.

I cannot get the latest Radeon driver to work with Haiku (18203) at all with my Radeon 9200 AGP. I also have an SB Live Value! in this machine - if that matters.

I had to revert 17279 and rebuild the driver in order to successfully boot Haiku with it again.

I'm thinking this bug is closed now?

9200 bug was hrev20336 #1079 and the backlight issue was semi-solved for those lucky people shortly later?

AFAIK there still are people with Back lights that don't function. I'd like to blame them on ACPI or other... ;)

I feel new tickets for those unlucky people would be easier for traceability, given the number of changes to the driver in the last 12 months. If anyone wishes to post a new ticket for backlight issues, can they post a syslog (with file name containing reporters name + laptop model). Everyone else just pile on more syslogs in a similar fashion.

If no objections I'll close this ticket.
