Created attachment 360222 [details] dmesg before switching with working vgaswitcheroo When friends asks why I have windows on my machines since I use always linux I said that I have Windows just for hardware failure detection. If something is not working on linux and I cant fix it I log in Windows that are only with default programs and check if it is working there. If it is not working on both systems then I have a hardware failure. After 10 days of trying and almost before a possible ruin of my notebook (I almost had in my hands on heat pistol on an attempt to try a reflow of dGPU (dedicated gpu) accidentally discovered that the previous one was a wrong assumption. I have a HP G62-b75ev notebook with hybrid with muxless i suppose 2 graphics cards that used to switch through vgaswitcheroo. Some fixing of disabling backlight on normal systems ruined mine. The problem was solved with recent patches and is described mostly at https://bugzilla.kernel.org/show_bug.cgi?id=55311 and at https://bugs.gentoo.org/show_bug.cgi?id=458746 where I firstly started. Unwilling to update kernel I stayed with patched kernel-3.10.0 with a working switch. After a usual update world that involved video drivers i faced the same problem again unable to fix whatever i tried. I decided to login to win7 since my bios hasn't an option about choosing what graphics card to use. As soon as logon of windows disappearance I faced the same black screen again. Able to login only on safe-mode. Disabling HD5470 login normally through intel but “stupid” windows force detecting new device and upon installing HD5470 screen turned black again. I tried the most ancient recover point I had. I loged in, I saw Bios EFI or Uefi update and after rest of updates I ended once again with black screen. Just before unscrewing my laptop to perform a dubious reflow of ATI gpu I noticed, during an accidentally startup on my gentoo, some warning about uvd, or something like that, that had to do with firmware. So before reflow I decided to check firmware more closly. I noticed about some CYPRESS_uvd.bin that I added to extra/firmware. Then I faced something about r600 failure and some ring_test failure ending always in black screen. I synced and updated all, I putted git (through 99999999) on firmware and hwids with same results. I tried downgrade kernel to 3.10.0 and firmware at the same time but somehow I couldn't compile kernel. I updated all, and after some try with windows that remain with black screen, before the try of unwilling reflow I connected an external screen. For my surprise second screen accepted dgpu out of the box with gentoo and decided to make a firmware downgrade as hard as I could. This time I forgot to take into consideration some compiling warnings and mostly to follow dmesg warnings about extra/firmware needing before I try switch. So after sys-kernel/linux-firmware-20130421, “make clean” and the last kernel I tried switch before trying to fix dmesg's firmware warnings. And voila!!! I had a WORKING desktop with dGPU. So my conclusion is. HP with some firmware update that I cannt control on Win7 ruined me as customer. Linux community somehow followed those updates with same result So some users like me may decide that dgpu is ruined since it is not working on both Oss and may ruin their notebook. Please Of course fill free to alter the title of this bug BUT dont erase sys-kernel/linux-firmware-20130421 from portage. I didnt check later firmwares and this time I am afraid of bisecting. Hope someone will do. Thank you

This is not a bug report. It's a blog entry.
To whoever reads this. It actually turned to be the start of hardware failure. I reflowed dgpu and this fixed the problem. Every time I update world laptop temperature raises too high. So half of the times dgpu wasn't working correctly giving the impression that ws update's fault. 2 to 3 times, specially when laptop powered violently off cause of hit and powered on without waiting to cool down, gpu was 'auto' fixed giving the impression that new configuration fixed it. Actually, the randomness of fixing and broking after too high temperatures of laptop pointed that it was a hardware problem and a reflow may be would solve the problem. And it did! Thank you
