Re: xenodm blank screen
Hi Ryan, Yes, please paste the output of: $ dmesg | less $ less /var/log/Xorg.0.log I see you already sent part of the Xorg log. Please send the entire output of the commands above. The information those provide will help us better assist you. Usually when you create your own ~/.xsession the main X config file /etc/X11/xenodm/Xsession won't start fvwm or xtem. so my .xsession starts xterm and cwm. xterm & cwm Additionally, do you have prior experience with cwm(1)? You can start a new xterm window with Ctrl-Alt-Enter or launch other apps (Firefox, Chrome) with Alt-? (Alt-Shift-/). Let us know the info above and if this explanation helps.

We are pleased to announce the official release of OpenBSD 7.4. This is our 55th release. We remain proud of OpenBSD's record of more than twenty years with only two remote holes in the default install. As in our previous releases, 7.4 provides significant improvements, including new features, in nearly all areas of the system: - Various kernel improvements: o On arm64, show BTI and SBSS features in dmesg(8). o New kqueue1(2) system call supporting the O_CLOEXEC flag. o Map device tree read/write to unbreak root on softraid(4). o Correctly recognize umass(4) floppy disk devices as floppy disks. o In wscons(4), catch up with box drawing characters which have been standardized in unicode after the original wscons code was written and chose placeholder values. o In wscons(4), make sure we do not increase the escape sequence argument count beyond usable bounds. o Implement dt(4) utrace(2) support on amd64 and i386. o Correct undefined behavior when using MS-DOS filesystems, fixes imported from FreeBSD. o Make the softdep mount(8) option a no-op. Softdep was a significant impediment to improving the vfs layer. o Allow unveil(2)ed programs to dump core(5) into the current working directory. o Address incomplete validation of ELF program headers in execve(2). o On arm64, use the deep idle state available on Apple M1/M2 cores in the idle loop and for suspend, resulting in power savings. o Update AMD CPU microcode if a newer patch is available. o Enable a workaround for the 'Zenbleed' AMD CPU bug. o Report speculation control bits in dmesg(8) CPU lines. o To give the primary CPU an opportunity to perform clock interrupt preparation in a machine-independent manner we need to separate the "initialization" parts of cpu_initclocks() from the "start the clock interrupt" parts. Separate cpu_initclocks() from cpu_startclock(). o Fix a problem where CPU time accounting and RLIMIT_CPU was unreliable on idle systems. o Improve the output of the "show proc" command of the kernel debugger ddb(4) and show both the PID and TID of the proc. - SMP Improvements o Rewrite pfsync(4), in particular to improve locking and to help with unlocking more of pf(4) and with parallelisation of the network stack in the future. The protocol remains compatible with the older version. o Remove kernel locks from the ARP input path. o Pull MP-safe arprequest() out of kernel lock. o Remove the kernel lock from IPv6 neighbor discovery. o Unlock more parts of ioctl(2) and the routing code in the network stack. - Direct Rendering Manager and graphics drivers o Update drm(4) to Linux 6.1.55. o Don't change end marker in sg_set_page(). Caused bad memory accesses when using page flipping on Alder Lake and Raptor Lake. - VMM/VMD improvements o Allowed vmm(4) guests to enable and use supervisor IBT. o Suppressed AMD hardware p-state visibility to vmm(4) guests. o Avoid use of uninitialised memory in vmd(8). o Migrate vmd_vm.vm_ttyname to char array allowing a vmd_vm object to be transmitted over an ipc channel. o Cleaned up file descriptor closing in vmd(8) vmm process. o Fixed vm send/receive, restoring device virtqueue addresses on receive. o Introduced execvp(3) after fork for child vm processes. o No longer generate an error in vmd(8) if vm.conf(5) is absent. o Split vmm(4) into MI/MD parts. o Introduced multi-process model for vmd(8) virtio block and network devices. o Allowed vm owners to override boot kernel when using vmctl(8) to start a vm. o Changed staggered start of vms to number of online CPUs. o Fixed a segfault on vm creation. o Switched to anonymous shared memory mappings for vmd(8) vm processes, introducing a new vmm(4) ioctl(2). o Relaxed absolute path requirements for vmd(8) configtest mode (-n). o Adjusted shutdown logic by vm id to function similarly as by name. o Moved validation of local network prefixes for the internal vmd(8) DHCP service into the config parser. o Fixed QCOW2 base images when used with the vmd(8) multi-process device model. o Fixed setting verbose logging in child processes. o Fixed a race condition related to the emulated i8259 interrupt controller by ignoring interrupt masks on assert. o Inlined pending interrupts in the vmm(4) ioctl(2) for running the vcpu, reducing vm latency. o Added zero-copy, vectored io to the vmd(8) virtio block device. o Changed to logging

Usually a complete shutdown and plugging and unplugging the power gets it to start working as expected.

7.4 on Mac M1 UTM (qemu) - X11
Hello, I see 7.4 has been released and has the new viogpu(4) driver by joshua stein. I am trying to use it in a VM created with UTM, a wrapper for QEMU that works on M1 Macs. The virtual machine installs and starts up fine from the install74.img mounted as a disk, but running startx/X/xenodm produces a black screen. in ~/.local/share/xorg/Xorg.0.log.old I see the following: Fatal server error: [ 419.659] (EE) xf86OpenConsole: No console driver found Supported drivers: wscons Check your kernel's console driver configuration and /dev entries(EE) [ 419.663] (EE) I am guessing creating an xorg.conf might help but I am not seeing anything about how to specify viogpu (virtio-gpu?) for that. I see this in dmesg: wsdisplay0 at viogpu0 mux 1: console (std, vt100 emulation) wsdisplay0: screen 1-5 added (std, vt100 emulation) Is X11 possible in this setup? It would let me run OpenBSD on a HiRes laptop. Thanks, John

It remains possible to simply not need to inspect those programs. I doubt setuid programs are being copied into a chroot jail. But, mostly I don't care because I'm sick and tired of 'bug reports' that don't explain the usage case. ldd's environment variable game has had holes, and all the valiant attempts we make will create holes in the future, I'd bet money on it.

There are two approaches. - use another tool to read the ELF header and parse NEEDED entries from that. several are available (including at least one which will recurse to show inter-library dependencies too, though I forget what it's called) - provide an alternative binary which _can_ be executed by ldd

Re: ldd error with setuid/setgid binaries
ldd around suid programs has a fine history of security holes.
One idea is for you to just not not do that.
You don't explain why you need to do this. You just completely skipped that.
You don't justify why you need it to work. Does that make me care?? No, it
really doesn't make me care.

I see. thank you.
I created and used a shell script to create a list of dynamic link
libraries used for all commands:
#!/bin/sh
[[ -z "$1" ]] && set /
find "$@" \
\! -fstype local -prune \
-o \
-type f \
\( -perm -100 -o -perm -010 -o -perm -001 \) \
-print \

/ELF 64-bit LSB shared object/ {print $1}' \
| xargs ldd \
| awk '
/^\/.*:$/ {fname = $1; sub(/:/, "", fname)}
$3 == "rlib" {print $7, fname}' \
| sort
But this no longer works properly on OpenBSD 4.7.
How can I solve this? Please let me know if you have any good
alternatives.

Not sure what you mean by setting a dark theme for Xorg, but AFAIK,
you don't theme Xorg, but rather your {window manager (in your case
cwm), desktop environment, widget libraries (gtk, qt)}. I don't use
cwm, but a quick search for 'color' in cwmrc(5) should give you an
idea of what colors you can configure. Other than that, some X
client applications such as xterm can be configured through
~/.Xresources.
Regarding #2, no clue. Sorry.

Dark theme in Xorg and trackpad
Hi list, # 1 Since a couple months ago I started using CWM, at first it was a little weird to use but now I find it hard to come back to fluxbox or I3, my favorite WMs...but (always one), I'd like to set Xorg (not GTK), in a dark theme, dunno if that's even possible...I've been a *BSD / linux user since '96-98... Never asked myself if that can be done... Any clue? # 2 I've have a Lenovo Ideapad 14W, which I use mainly to pentesting, It works flawessly with OpenBSD...X, suspend, network...everything...but (again), I can't get the trackpad to work...There is a 70-synaptics.conf under /usr/X11R6/share/X11/xorg.conf.d, but I'm not sure if it has any effect at all. Again, any clue to start working on it? Thnx!!! P. PS... Upgrade to 7.4 flawless...not a single problem and so far seems that general performance is even better than 7.3, amazing.

Re: xscreensaver-settings keeps on crashing
I discovered that if I run xfce desktop that I have on here for thunar file manager, that it works. I don’t know why. I can’t run xscreensaver-settings under fvwm. The screensavers work though. Any suggestions? It said something about conflicting with xfce4-screensaver or something too.

X session doesn't survive zzz
This is current/amd64 on a PC (dmesg below). After a resume from zzz inside a running X session, I am greeted with the xenodm login screen into which I cannot login: the keyboard does nothing (is it the USB keyboard not reattaching properly?). Loging in on the console, I see that the X session and the X applications (firefox, xterms) are dead. On the other hand, the mplayer that has been zzz'ed inside a tmux session starts playing again. After restarting xenodm with rcctl restart xenodm, I can log in and everything seems to work again. See the dmesg below, including the zzz and resume, and the full X log up to here. How can I debug this?
