Re: Xvesa black magic
Apparently xinit was eating a lot of potentially useful output. Anybody able to extract anything meaningful from this session? # Xvesa -mode 0x117 -kb -mouse mouse,/dev/input/mice Int 10h (0x4F10) failed: 0x014F (function call failed) No DPMS Support -1 FreeFontPath: FPE "build-ins" refcount is 2, should be 1; fixing. # Xvesa -mode 0x117 -mouse mouse,/dev/input/mice Mouse device is serial port, protocol exps/2 is not serial protocol Int 10h (0x4F10) failed: 0x014F (function call failed) No DPMS Support -1 FreeFontPath: FPE "built-ins" refcount is 2, should be 1; fixing. # Xvesa -mode 0x117 Int 10h (0x4F10) failed: 0x014F (function call failed) No DPMS Support -1 FreeFontPath FPE "built-ins" refcount is 2, should be 1; fixing. For those who came in late, this is under Qemu. I had to retype the output (Qemu doesn't seem to support copy-paste from a console session, hehe) so I hope there's no typos in there. Once Xvesa is launched, I can't make it respond to ctrl-alt-backspace signals from Qemu; to get at the output above, I had to launch "sleep 30; pkill X" in another terminal before each time I launched X. I have other people's builds of Xvesa running happily under the same emulator, so I can't see that the problem is with the emulator. I don't know off the top of my head where I can look up kernel calls (and Google isn't helping right now) so I don't know what 0x4F10 does. (I'm going to guess that it involves video mode setting--if I leave off the -mode flag, the server goes into a loop making failing 0x4F10 calls, which I assume is a symptom of a failed autodetect routine.) Also, the "Mouse device is a serial port" message is interesting. I can't seem to find any other magic combination of flags that triggers that message; it makes me wonder if the mouse device I'm pointing Xvesa at is not what I think it is. If anyone can point me in the right direction to continue debugging this, I would be very grateful. -- William Tracy afishion...@gmail.com -- wtr...@calpoly.edu Vice President, Cal Poly Linux Users' Group http://www.cplug.org "I disapprove of what you say, but I will defend to the death your right to say it." -- Evelyn Beatrice Hall, frequently mis-attributed to Voltaire ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Xvesa black magic
Hello all, I'm playing with an Kdrive-based image of mine under Qemu. I built Xvesa from the 7.3 release of Xorg, as 7.4 seems to have a regression in TinyX (that's a topic for another email). I'm building the images using the T2 SDE framework, if that's meaningful to anyone. Everything compiles fine. I am able to launch Xvesa just fine ... but I get no mouse input. It does not respond to a ctrl+alt+backspace signal or a ctrl+alt+F signal (which works before the server starts). Finally, I resorted to launching: sleep 30; pkill X in one console, while launching Xvesa from another console. This at least allowed me to see the output from Xvesa, after the script killed the server: Couldn't find the keyboard driver keybd Could not init font path element blablabla Could not init font path element blablabla X server does not support locale cannot set locale modifiers blackbox: managing screen 0 using TrueColor visual 0x21, depth 16 X connection to :0.0 broken (explicit kill or server shutdown). xinit: conection to X server lost. waiting for X server to shut down The X11 startup script I'm using is: #!/bin/sh . /etc/profile # PATH HOME=/root # ??? # on x86* we usually could use Xvesa, otherwise we rather need Xfbdev if [ -d /sys/class/graphics/fb0 ]; then X="Xfbdev" else X="Xvesa -mode 0x117" fi cd $home xinit `which blackbox` -- `which $X` -mouse mouse,/dev/input/mice -keybd keyboard I have confirmed that it is Xvesa, and not Xfbdev that is being launched, and I have tried every conceivable variation on the server parameters at this point. Now, what really puzzles me: in spite of the error message, I can force a response to keyboard input. If I launch an xterm and no window manager, I can force the xterm to get key focus, and I can type into it. However, nothing I can do will make the mouse respond to motion or to clicks. So, any thoughts on whether this looks like a kernel configuration issue, a build configuration issue, or just a run-time X configuration issue? If anyone is *really* motivated to help :-) I can try to get you a copy of the image I built and/or the configuration I used to build it. -- William Tracy afishion...@gmail.com -- wtr...@calpoly.edu Vice President, Cal Poly Linux Users' Group http://www.cplug.org "I disapprove of what you say, but I will defend to the death your right to say it." -- Evelyn Beatrice Hall, frequently mis-attributed to Voltaire ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Just thinking out loud here: If desktop session management were good enough, even open windows could be "persisted". Even better would be if there were a mechanism to transparently disconnect an app from one X session, wait for X to restart, and then attach it to the new session. Probably doable at the toolkit level, but that doesn't help with all the zillions of apps written against legacy toolkits. Random idea: There are already several special-purpose X servers that run on top of Xorg supporting special magic like hardware compositing. What if there were a server that could dynamically dispatch to/from different Xorg instances? It would notice when Xorg dies, and stop sending it events. When a new Xorg launches, it would send a series of "new window" commands, and attach all of its clients to those windows. Right now I'm assuming that both cards would support equivalent resolutions and color depths. If not, then never mind. :-P Anyway, I agree that restarting the server is less painful than a full reboot. -- William Tracy afishion...@gmail.com -- wtr...@calpoly.edu Vice President, Cal Poly Linux Users' Group http://www.cplug.org "I disapprove of what you say, but I will defend to the death your right to say it." -- Evelyn Beatrice Hall, frequently mis-attributed to Voltaire ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

new Xorg + btnx
http://ubersoft.net/void-initrand/misc-wherein-i-curse-ubuntu-needlessly-breaking-something-useful 1. I don't use btnx, so I don't share his problem. Ask him for details, not me. 2. The root of the problem seems related to changes in Xorg, so I thought I'd pass it along. If it actually has more to do with a Linux kernel change, my apologies for spamming the list. Short summary: btnx is a program for remapping extra mouse buttons to different actions. A recent Xorg release (supposedly related to the introduction of evdev) seems to break the API it depends on. Now, if there's just a *different* API available now for accessing raw mouse input, and the user-visible applications just need to catch up, then fine. However, if this information is simply no longer available to clients, then this list should at least be aware of the issue.

In many ways, Xorg sure seems like an operating system kernel when you look at it under the hood; it has a separation of "kernel space" and "user space" (server and clients talking via sockets), it has drivers, and it even has its own task scheduling algorithm (!!!). That said, Xorg is moving *away* from being an "entire operating system", if anything. There is a push to move most of the drivers into actual kernel space, and some of the work Red Hat is doing seems to push half of the X server into the kernel. (I'm not that familiar with Wayland, so no doubt "half of the X server" is a gross exaggeration, but my basic point still stands.) -- William Tracy [EMAIL PROTECTED] -- [EMAIL PROTECTED] Vice President, Cal Poly Linux Users' Group http://www.cplug.org "I disapprove of what you say, but I will defend to the death your right to say it." -- Evelyn Beatrice Hall, frequently mis-attributed to Voltaire ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
