* screen goes blank when loading gma500_gfx (atom D2500) @ 2014-02-08 19:56 Michael Tokarev 2014-02-10 10:44 ` One Thousand Gnomes 0 siblings, 1 reply; 16+ messages in thread From: Michael Tokarev @ 2014-02-08 19:56 UTC (permalink / raw) To: Linux-kernel, dri-devel Hello. Today I rebooted my router into a new kernel and noticed that the screen goes blank after booting the system (initial bootup messages are visible). After some debugging it turns out that the screen goes blank when loading gma500_gfx module. This is an intel D2500CC motherboard with Atom D5200 built-in, with a monitor connected to a VGA port, the following vga device is reported by lspci: 00:02.0 VGA compatible controller: Intel Corporation Atom Processor D2xxx/N2xxx Integrated Graphics Controller (rev 09) Here are the dmesg output after loading gma500_gfx: [ 176.427071] Linux agpgart interface v0.103 [ 176.452914] [drm] Initialized drm 1.1.0 20060810 [ 176.476037] gma500 0000:00:02.0: setting latency timer to 64 [ 176.476216] gma500 0000:00:02.0: irq 50 for MSI/MSI-X [ 176.491675] acpi device:29: registered as cooling_device2 [ 176.492041] ACPI: Video Device [GFX0] (multi-head: yes rom: no post: no) [ 176.492169] input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:00/input/input11 [ 176.492357] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

I tried 3.10 kernel initially (the above messages are from it), next I tried 3.13 kernel too, and that one behaves exactly the same. As far as I remember, this system never worked with graphics well. Previous kernel (from which I updated) was 3.2 which had no gma500 module (local build). What are the steps to debug this further?

In 3.13 I had X86_SYSFB set to y initially (SIMPLEFB doesn't exist there too), but setting it to n does not make any difference. > Boot with drm.debug=6 > > collect the logs I used `modprobe drm debug=6' (initially booting with gma500_gfx module disabled), followed with `modprobe gma500_gfx'. After loading module the screen goes blank as before, and monitor says 'no signal detected'.

It's been 4 more months since last message in this thread (which was mine). Now kernel 3.16 has been released, and I decided to give it a try. And it behaves just like all previous kernels, -- once gma500_gfx module is loaded, screen goes blank, monitor turns off ("no signal detected") and nothing to be seen until reboot. Can we try to debug this somehow, after more than half a year?... :) Thank you, /mjt 05.04.2014 12:15, Michael Tokarev wrote: > Hello again > > It's been about 2 months since I sent the original debugging output.

If that makes the difference on your box can you send me a dmidecode of it, and I'll see if we can at least teach the driver that the 2500CC needs LVDS enabled regardless of what the BIOS reports. ^ permalink raw reply [flat|nested] 16+ messages in thread

I think you mean disable, not enable, since this is (again, I think) what video=LVDS-1:d kernel boot parameter does. Yes, with video=LVDS-1:d boot parameter, kernel boots fine and there is graphics/video output on the screen, with the following message from kernel when loading gma500_gfx: [ 6.472859] [drm] forcing LVDS-1 connector OFF (and a few others). There's one funky thing still -- the screen size is not calculated correctly for the text (vga, d-sub) console, last text line is placed at about 3/4 of the screen size, with the rest - 1/4 - of the screen being blank. However, X seems to work fine, using generic modesetting driver. Below is dmidecode output.

I've seen that in one other case, where what was in fact happening was that forcing the connector "off" was actually effectively leaving it as the BIOS set it. What happens if you then use xrandr to change the display sizes ? Alan ^ permalink raw reply [flat|nested] 16+ messages in thread

When I use LVDS-1:d in the kernel command line, that connector is not shown by utilities such as xrandr, at all. There is, however, another connector, named LVDS-0, and are also DVI-0, DVI-1, and DisplayPort-0, DisplayPort-1, while this mobo only have DVI & D-SUB (and LVDS soldered on board too) and no DP. At least as far as I can see. So at least one LVDS connector is shown anyway (LVDS-0, not LVDS-1), and that one is "not connected". Besides, DisplayPort-1 is shown as "connected" by xrandr, with monitor set to 1024x768 mode, -- I think this is why the text VGA size is calculated wrong.. Lemme see... ..nope. Adding video=DisplayPort-1:d to the kernel command line (in addition to video=LVDS-1:d) makes no difference, DisplayPort-1 is still shown by xrandr as connected @1024x768. > What happens if you then use xrandr to change the > display sizes ? X11 works fine as far as I can see. Xrandr works and changes video modes. Once I switch from X back to the text console the text size occupes 3/4 of the screen only, as if the monitor was smaller. I wonder if it will work with more than one monitor... ;) I'll try hopefully today. Thanks, /mjt ^ permalink raw reply [flat|nested] 16+ messages in thread

Ok. actually this is not so simple. Yes, LVDS:d makes a difference. Namely, it enables monitor connected to VGA-0 to function. But once I plug in a digital monitor (DVI-0), screen goes blank when loading the module again, and this time, it does not matter whenever I specify any video= options (trying to disable any combinations of listed adaptors), screen is always blank. So basically the thing is still unusable. Because d-sub connection isn't stable (picture "trembles" depending on the cable and environment conditions), while digital option does not work. In bios, there's an option to ENable LVDS (it is disabled by default) and once enabled, to make it primary or secondary (with either automatically or manually choosen secondary/primary, being d-sub or dvi). When I enable LVDS with any other monitor in bios, the thing does not work again, the same way (screen goes blank once the module is loaded), but now d-sub/vga monitor does not work too. Ouf of curiocity I tried to run windows7 on this machine. Apparently it works with dvi monitor just fine and supports configuration with 2 monitors. Maybe they have some quirks in the drivers, I dunno... Thanks, /mjt ^ permalink raw reply [flat|nested] 16+ messages in thread
