Hello, Very similar situation here with an ASRock N3150M motherboard. This board has DVI, HDMI and VGA ports, of which I'm using just the DVI. The Xubuntu 18.04 Bionic Beaver i386 DVD fails to bring up the window manager with a GPU hang. What works: nomodeset What doesn't: bootstring intel_iommu=off (a solution proposed elsewhere)
When nomodeset is NOT used, nine times out of ten a single underscore character appears at the top left of the screen and the kernel is unresponsive (Alt-SysRq-h does nothing), however it is occasionally possible to get a mouse pointer on a blank screen and switch to console from there. I was able to retrieve /sys/class/drm/card0/error and will attach. Also some related info from logs, please see below. Regards. ====================================== from dpkg.log ------------- linux-image-4.15.0-20-generic:i386 4.15.0-20.21 libx11-6:i386 2:1.6.4-3 xserver-xorg:i386 1:7.7+19ubuntu7 xserver-xorg-core:i386 2:1.19.6-1ubuntu4 xserver-xorg-video-vesa:i386 1:2.3.4-1build3 xserver-xorg-video-intel:i386 2:2.99.917+git20171229-1 i965-va-driver:i386 2.1.0-0ubuntu1 libgl1-mesa-glx:i386 18.0.0~rc5-1ubuntu1 libdrm2:i386 2.4.91-2 libwayland-server0:i386 1.14.0-2 lightdm:i386 1.26.0-0ubuntu1 lightdm-gtk-greeter:i386 2.0.5-0ubuntu1 from lspci -vnn --------------- 00:02.0 VGA compatible controller [0300]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller [8086:22b1] (rev 21) (prog-if 00 [VGA controller]) Subsystem: ASRock Incorporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller [1849:22b1] Flags: bus master, fast devsel, latency 0, IRQ 120 Memory at 90000000 (64-bit, non-prefetchable) [size=16M] Memory at 80000000 (64-bit, prefetchable) [size=256M] I/O ports at f000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 from lshw --------- *-display description: VGA compatible controller product: Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 21 width: 64 bits clock: 33MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:120 memory:90000000-90ffffff memory:80000000-8fffffff ioport:f000(size=64) memory:c0000-dffff from dmesg ---------- [ 0.000000] Linux version 4.15.0-20-generic (buildd@lgw01-amd64-033) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #21-Ubuntu SMP Tue Apr 24 06:15:38 UTC 2018 (Ubuntu 4.15.0-20.21-generic 4.15.17) [ 0.000000] ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Gpe0Block: 128/32 (20170831/tbfadt-603) [ 0.140275] pci 0000:00:02.0: vgaarb: setting as boot VGA device [ 0.140275] pci 0000:00:02.0: vgaarb: VGA device added: decodes=io+mem,owns=io+mem,locks=none [ 0.140321] pci 0000:00:02.0: vgaarb: bridge control possible [ 0.140417] vgaarb: loaded [ 16.996226] [drm] Memory usable by graphics device = 2048M [ 16.996329] [drm] Replacing VGA console driver [ 16.997434] Console: switching to colour dummy device 80x25 [ 16.997628] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
