Using integrated Intel GFX and dedicated PCI GFX card not possible

[Alexco]

I have a AMD Radeon 280x installed as primary graphics device with 2 monitors attached. If I enable Intel integrated GFX (without attached monitor) the system hangs during boot (all icons on) with hrev53209.

It seems that Haiku uses the integrated graphics as primary display, even if no monitors are attached, and even while BIOS initialised the Radeon as primary display. Blacklisting the Intel_Extreme driver works, screen is then presented on Radeon without issue (albeit only 1 monitor can be used). Bootlog with Intel_Extreme and without attached.

intel_extreme: engine locked up, head a8!

Please check with a current nightly, and provide a syslog.

hrev55956 syslog with Radeon5500

Retested with hrev55956. But in the meantime my R9 graphics card died, so I tested with my 5500 card. But this is currently unsupported so I enabled the "Fail Safe Video" setting. So I don't know how feasible this retest is. But as a result, Haiku now boots up without delay or issues, syslog attached.

If the radeon_hd driver is disabled, the framebuffer and intel_extreme drivers should both be loaded. What the app_server will do with them is a good question.

[Alexco]

At least both graphic card devices are listed in the Devices Application, and I can use Haiku with the framebuffer device without issues.

Retested with hrev56771, system now boots without issue, also without "Fail Safe Video". Can be closed now, I guess.
