Summary: No display with switcheroo Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: mike@fireburn.co.uk

Hi
I've gotten a new laptop - HP Envy 14 2002ea
I've configured my kernel for the Intel and Radeon graphics and enabled the switcheroo option too
When booting the kms screen with Tux at the top shows for a split second before going blank - fortunately I can SSH in - also nomodeset works
I'm going to attach the lspci, dmesg and xorg.log for both set as the default
I've also changed the bios setting between Dynamic and Fixed but it's made no difference
If you need any more information please let me know

--- Comment #4 from Michael Lothian mike@fireburn.co.uk 2011-10-04 16:49:18 PDT --- I should probably mention that I'm running git master from Linus' tree last updated 6 hours ago with your fixes (I've tried with and without those fixes)
Unfortunately as this is a new laptop I don't know if this is a regression or not

--- Comment #5 from Alex Deucher agd5f@yahoo.com 2011-10-04 17:01:26 PDT --- You have a muxless laptop which means the discrete card is not connected to any displays. You won't be able to use the discrete card until the xserver gets the ability to decouple rendering and display (i.e., rendering with one GPU, displaying with another). It's a huge amount of work and won't be supported any time some.

--- Comment #6 from Michael Lothian mike@fireburn.co.uk 2011-10-04 18:33:20 PDT --- How do I use the Intel graphics as default?

--- Comment #7 from Michael Lothian mike@fireburn.co.uk 2011-10-05 01:20:52 PDT --- OK I've tried only compiling the intel drm on it's own and also the radeon drm on it's own, both with and without vgaswitcheroo and each of those were tested chaning the bios options between fixed and dynamic
Only when both are compiled in and vgaswitcheroo enable do I get a quick flash of a KMS screen before going blank
Intel only goes blank, looks like it is mode setting however
Radeon only doesn't modeset but segfaults unless nomodeset is passed
I'm now running X using the mesa driver :-(
I can live without the power of the Radeon card until xorg or wayland supports render and display on two GPUs, I just need to know how to force Intel to do modesetting

--- Comment #8 from Cedric Sodhi manday@gmx.net 2011-10-05 01:36:13 PDT --- Is this perhaps a duplicate of #41306 ?

--- Comment #9 from Michael Lothian mike@fireburn.co.uk 2011-10-05 03:16:22 PDT --- I'll try the lid tonight - is there any other way to force the backlight on if it is the issue?

--- Comment #10 from Cedric Sodhi manday@gmx.net 2011-10-05 04:43:00 PDT --- I know of no reliable way to bring the backlight on, particularly because the actual problem has not yet been determined. However, if you have an external monitor you may try to attach it to VGA on boot and see whether you can see the clone there. If so, you can at least experiment with xrandr, as I described in the bug. Read it carefully, it also is relevant how the laptop is currently supplied [1]. If it turns out to be the same bug as Bug #41306 , please close this one here as a duplicate so that efforts are concentrated and the number of affected users can clearly be seen.

--- Comment #11 from Alex Deucher agd5f@yahoo.com 2011-10-05 06:25:01 PDT --- Please open a new bug for backlight problems otherwise things will get confused as this started out as a vgaswitcheroo bug.

--- Comment #13 from Michael Lothian mike@fireburn.co.uk 2011-10-05 19:51:32 PDT --- Yes it was the backlight - fortunately for me the buttons on my laptop work at increasing the brightness thanks to hp-wmi
Now I just need to figure out how to make it always boot with the backlight on
Thanks for the help
