i sent this to bugs@ but it didn't seem to get posted. granted that it has only been a few hours, but that is the second time in two days, so i am taking a chance sending it here instead.
this is related to the first report i sent, which others experienced too. (https://marc.info/?l=openbsd-misc&m=143186792526486&w=2). someone reported this first issue was fixed for him, but i am apparently still experiencing something (i downloaded from the same source). >Synopsis: console/X go blank and will not display after switching >Category: display >Environment: System : OpenBSD 5.7 Details : OpenBSD 5.7-current (GENERIC) #843: Sun May 17 20:46:15 MDT 2015 [email protected]:/usr/src/sys/arch/i386/compile/GENERIC Architecture: OpenBSD.i386 Machine : i386 >Description: the console works until you switch to X, which works fine until you switch back to console, then everything is blank. input still seems to work right. >How-To-Repeat: switch to X, switch back to console >Fix: dmesg: OpenBSD 5.7-current (GENERIC) #843: Sun May 17 20:46:15 MDT 2015 [email protected]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Celeron(R) CPU 2.80GHz ("GenuineIntel" 686-class) 2.81 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,CNXT-ID,xTPR,PERF real mem = 527908864 (503MB) avail mem = 507011072 (483MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: date 02/25/04, BIOS32 rev. 0 @ 0xfb940, SMBIOS rev. 2.3 @ 0xf0000 (40 entries) bios0: vendor Phoenix Technologies, LTD version "3.08" date 02/25/2004 bios0: Compaq Presario 061 DW263A-ABA S7300CL NA510 acpi at bios0 function 0x0 not configured mpbios0 at bios0: Intel MP Specification 1.4 cpu0 at mainbus0: apid 0 (boot processor) mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 100MHz mpbios0: bus 0 is type PCI mpbios0: bus 1 is type PCI mpbios0: bus 2 is type ISA ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 20, 24 pins pcibios0 at bios0: rev 2.1 @ 0xf0000/0xdbb4 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfdae0/192 (10 entries) pcibios0: PCI Exclusive IRQs: 3 5 9 10 11 pcibios0: PCI Interrupt Router at 000:31:0 ("Intel 82371SB ISA" rev 0x00) pcibios0: PCI bus #1 is the last bus bios0: ROM list: 0xc0000/0xb400 0xcc000/0x8000! pci0 at mainbus0 bus 0: configuration mode 1 (bios) pchb0 at pci0 dev 0 function 0 "Intel 82845G Host" rev 0x03 vga1 at pci0 dev 2 function 0 "Intel 82845G Video" rev 0x03 intagp0 at vga1 agp0 at intagp0: aperture at 0xe0000000, size 0x8000000 inteldrm0 at vga1 drm0 at inteldrm0 error: [drm:pid0:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 130 Raw EDID: 00 ff ff ff ff ff ff 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff error: [drm:pid0:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 130 Raw EDID: 00 ff ff ff ff ff ff 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff error: [drm:pid0:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 130 Raw EDID: 00 ff ff ff ff ff ff 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff error: [drm:pid0:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 130 Raw EDID: 00 ff ff ff ff ff ff 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff drm:pid0:drm_do_get_edid *WARNING* VGA-1: EDID block 0 invalid. inteldrm0: 1024x768 wsdisplay0 at vga1 mux 1: console (std, vt100 emulation) wsdisplay0: screen 1-5 added (std, vt100 emulation) uhci0 at pci0 dev 29 function 0 "Intel 82801DB USB" rev 0x02: apic 2 int 16 uhci1 at pci0 dev 29 function 1 "Intel 82801DB USB" rev 0x02: apic 2 int 19 uhci2 at pci0 dev 29 function 2 "Intel 82801DB USB" rev 0x02: apic 2 int 18 ehci0 at pci0 dev 29 function 7 "Intel 82801DB USB" rev 0x02: apic 2 int 23 usb0 at ehci0: USB revision 2.0 uhub0 at usb0 "Intel EHCI root hub" rev 2.00/1.00 addr 1 ppb0 at pci0 dev 30 function 0 "Intel 82801BA Hub-to-PCI" rev 0x82 pci_intr_map: bus 0 dev 30 func 0 pin 1;
