In light of the security announcement I wanted to update from commit c52a2b1eba to c1455f76c6. But with the latter my screen stays black. In fact, the connector (DVI-D) seems to get disabled, since my monitor shows the "searching for signal" screen, where it cycles through its inputs. I can't even access the TTYs. There is no error logged to Xorg.0.log nor dmesg. Reverting (via SSH from another machine) to a build of c52a2b1eba gives me back access to the TTYs and a KDE session without a reboot. Just launching the older X.org is enough. The failing stack was (Debian testing as a base, fully updated): GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Mesa: Git:master/a2f2eebfdf libdrm: Git:master/00847fa48b LLVM: SVN:trunk/r223220 (3.6 devel) X.Org: Git:master/c1455f76c6 Linux: Git:<git://people.freedesktop.org/~agd5f/linux>:drm-next-3.19-wip/f66d9660a0 Firmware: <http://people.freedesktop.org/~agd5f/radeon_ucode/> > 9e05820da42549ce9c89d147cf1f8e19 hawaii_ce.bin > c8bab593090fc54f239c8d7596c8d846 hawaii_mc.bin > 3618dbb955d8a84970e262bb2e6d2a16 hawaii_me.bin > c000b0fc9ff6582145f66504b0ec9597 hawaii_mec.bin > 0643ad24b3beff2214cce533e094c1b7 hawaii_pfp.bin > ba6054b7d78184a74602fd81607e1386 hawaii_rlc.bin > 11288f635737331b69de9ee82fe04898 hawaii_sdma.bin > 284429675a5560e0fad42aa982965fc2 hawaii_smc.bin libclc: Git:master/229064524b DDX: Git:master/c9f8f642fd Let me know, if you need something else.
Probably the glamor ABI breakage fixed by http://lists.x.org/archives/xorg-devel/2014-December/044808.html . If so, you should see a message about glamor_egl_destroy_textured_pixmap being unresolved in the Xorg stderr output.
Please reopen if it still happens with this fix: commit 91651e7c15892aa846fc406fbb13b37f094dd3f0 Author: Michel Dänzer <michel.daenzer@amd.com> Date: Wed Dec 10 16:21:44 2014 +0900 glamor: Reinstate glamor_(egl_)destroy_textured_pixmap They are part of the ABI.
