I've been experimenting with the newer 2.6.22.x kernels on my PCLOS install. Mostly moms been installing them because the 2.6.20.x kernels were very stable & added some nice power use things i think.

However anything AFTER that kernel series so far makes my screen freeze up then unfreeze at seemingly random intervals. What gives? Ideas? Anyone had any luck with this kernel series or is it nexuiz?

Thanks!

I'm using 2.6.22-14-generic. I found that that happened when I had a wine application running while I had avant window navigator running. Dunno if that's your problem but other then that it's smooth sailing for me...

EDIT: this started happening when I upgraded the kernel after ubuntu gutsy came out...

Thanks Psych but I don't have any of that going on. Just running fluxbox and nothing else except for audacious (an music player). So I'm wondering if maybe I should just compile nexuiz myself with my new kernel?

If I wanted to do that where do I get instructions on how to do so please?

well, maybe a process is causing it. is it while playing nexuiz alone?

I don't play any other games under linux but I guess I could try warsow...I hadn't thought of that actually. I'll give it a try tommorow & let you know.

What graphics card, which driver version, which X version?
I'm using 2.6.21.3 on my PC, and 2.6.23.1 on my laptop, both without any problems.
When I started using 2.6.23, i used 2.6.23-rc3, and had to use a patch for the nvidia drivers, but with the current ones and 2.6.23.1 I have no problems at all.

And for compiling, you simply unpack the engine***.zip file, it's in the released .zip file
then cd into darkplaces, and do `make`, that shows you a list of what you can do, eg: `make sdl-release` will build a binary that uses libSDL
Then you get a darkplaces-sdl or darkplaces-glx, or whatever from that, which you can use.

Ubuntu Hardy Heron running without problems of any kind.

I updated my Ubuntu Studio to 7.10, with generic kernel 2.6.22.x (not exact, I'm at work right now away from that machine), it was working fine, I even got Compiz installed and running (from the repository, really easy). I'm guessing the screensaver was on, and Nexuiz after a while of playing, went from full screen to a small window, and then the entire screen went blank, I had to kill X Windows with ctrl+backspace, and then I rebooted the machine. I need to go back and test it some more myself.

Also, I noticed that Nexuiz 2.3 is now part of Ubuntu repository.

Archlinux version Blah (rolling-release system), custom 2.6.23.1 kernel with -rt5 realtime patch* (Ingo Molnar's stuff) plus git-hid patches from -mm tree (dude, I have an MS Natural 4000 w/ all the gizmos! I need me extra buttons! ). If I have problems, they are strictly the result of a poor upbringing.

*I do audio work and I hate having to boot into one of several kernels to get some particular feature. I use a realtime priority wrapper to start anything that doesn't properly set up its own PRI. It was quite sweet when using PS/2 keys/mouse, but with my switch to USB peripherals I'm noticing more stuff I'll probably either need to tweak or ditch to be happy with it again. And yes, for the curious, Nex can be run realtime, but there's simply no point in it. You're better off adjusting security limits for your user and starting Nex with a highish negative nice - and if you run Nex out of a custom .xinitrc like I do and don't have a window manager chewing cycles, there's probably no point in that either.

OK Bender BREAAAAAAAAAAAATHE .... sorry i love you but you kinda lost me in the geek talk. Teach me Oh Guru!!!

I put in the older 2.6.20.18 kernel & all my issues went away. Soooo what ever they're putting into the newer kernels either doesn't like nexuiz OR the pclos dev team messed up somewhere. This isn't a gaming distro and well i considered running slackware but i don't know if i'm ready for that yet. Not sure I can be my own security sys admin, kernel updater, etc by myself yet. Mom helps alot sure but shes not perfect you know? And relying on her isn't fair.

sigh

oh well it works on this kernel from the pclos devs and I just don't get why it doesn't on the newer ones. bleh

strange thing i noticed:
i can't use audacious when playing nexuiz, audacious causes freezes! Maybe you should check this: open termial, launch glxgears.
without audacious i get around 12000, with audacious running i get around 2000 fps and freezes. Audacious with nexuiz worked correctly on ubuntu 7.04, now on ubuntu 7.10(2.6.22-14-generic) i can't use this player when I'm going to use some application with 3d acceleration.

As a curious thing, I get the same issue as you with Amarok. My nexuiz freezes for a minute when it changes songs (I use a radio stream when playing). I picked audacious specifically because it has little impact on performance so I was surprised to see you write this.

Did my own test and on a 2.6.20.18.dev1.ck (Con Kolvas patches) kernel running PCLOS 2007 (fully up to date except for the kernel) I get this -

glxgears {with audacious running}
40400 frames in 5.0 seconds = 8079.985 FPS
40073 frames in 5.0 seconds = 8014.579 FPS
40462 frames in 5.0 seconds = 8084.716 FPS

glxgears {without audacious}
44155 frames in 5.0 seconds = 8830.952 FPS
43968 frames in 5.0 seconds = 8793.493 FPS
44112 frames in 5.0 seconds = 8822.400 FPS

Its an 800fps improvement sure but I get little other improvement and nexuiz runs fine with or without audacious running so it must be something Ubu did as in my case it seems its something PCLOS did to the kernels.

maybe it's the sound server? try switching to something else temporarily just to see what happens

I'd bet a little money these audio/video performance hits are being caused by bus contention - an IRQ shared that shouldn't be. And it probably isn't either the sound or video card but the usb host. Am I correct in assuming you're using usb keys/mouse?

On my new mobo I've run into these problems when trying to use a usb keyboard & mouse - and despite having a bit of control through bios and being able to tell the kernel to grok & honor bus setup from bios, i still end up with irqs that should be bound only to one address space being piggy-backed by the usb host, which is F*CKING AWFUL.

I have a couple theories for you Summer Willow.

1) I've had some issues w/ Amarok running while playing Nexuiz, due to it updating my collection every X interval, which is something like every 5-10 minutes. Random Play is much worse, which rescans every time the song changes. You can disable the auto-scanning and random play, but I just kill Amarok.

2A) A lot of kernel options changed from 2.6.19 to 2.6.23. I've heard a few people recently complaining of similar problems. For them, one of the I/O schedulers (CFQ, Anticipatory, Deadline) are bad and simply changing to another fixes the problem. You may try that.

2B) Because of the changes, blindly copying your .config to the new kernel may not work. For me, a lot of the iptables broke until I figured out where everything moved. Some options were only enabled by enabling other options that only got enabled by other options...

2C) Check your SATA/PATA drivers. These have changed both in location and availability. On some of my machines the next generation SATA/PATA worked great and the old ones no longer work, or cause crashing. On other machines I've found I can't use the new drivers, while I've also found some machines where I have to mix and match new SATA with old PATA or vice versa.

Side note/OT: I have had some issues w/ kernel 2.6.23 specifically and packages that taint the kernel like nvidia-drivers, madwifi/ndiswrapper, fuse, etc. They cant seem to find the kernel. This may be a gentoo specific problem with gentoo-sources-2.6.23 as I dont have the problem w/ the -r1 version bump, or older versions. I never found anyone else with this problem when searching on forums but I figured I'd throw this out there for anyone to confirm the same problem.

If you're still checking this thread, check which vesion of Xorg you're running, I've come across some real probs in 7.3. "Xorg -version" from console should give you the version... And see if you can get the xorg-server version itself via your package management system. xorg-server-1.4 series has been pretty bad, IMHO. If you're running that version and it's feasible to rollback to an earlier version, do so (YMMV! I don't want BB yelling at me cuz you messed it up!).
