There are various tests, from glxgears to glmark2 to Unigine Benchmark, which will put a graphics card through its paces and of course test the video driver with it. If by running any of these you get the same symptoms I would think the problem is specific to your GPU/driver and perhaps how it uses shared memory - hence the beep. You can also see if there is a momentary jump in memory usage by using vmstat, watch -d ipcs -m, watch -d cat /proc/meminfo, et al. Glitches like these usually go away after a while, when the application, Xorg drivers and occasionally the kernel get updated to a later version. Other than that you could start debugging apps and drivers, which often ends up being a ping-pong between video driver devs, app devs and desktop devs. I'm not I can offer more practical help, but others more knowledgeable in this field may be able to contribute. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

If it is a BIOS beep, rather than a desktop/application sound, then you have some hardware problem. The recent update may have implemented some hardware acceleration rendering on the browser and this is putting pressure on your GPU, RAM, PSU. A single beep points to RAM, but I don't know all OEM's BIOS codes. I'd start by opening the cover and reseating your RAM modules. Oxidisation may have increase contact resistance. Usually pulling them out and pushing them back in cleans them enough to restore a good electrical contact. While you're there try removing all the dust from CPU, GPU, PSU coolers and air ducts using a vacuum cleaner (carefully) or a compressed air can. Keep holding the chassis at all times with one hand or use an earthing strap, some vacuum cleaners I've tried have a terrible problem with creating static electricity and a discharge could blow your MoBo chipset Finally, reseat any SATA/IDE cables. Their contacts can also corrode with time and if the browser is caching pages on disk while the freeze occurs it might cause a problem, although unlikely to get a BIOS beep from it. You wouldn't be able to boot with a hard disk failure beep code going off, if this was your problem. Single beep would mean RAM issue indeed if it's a BIOS beep. But the fact that it happens only when using the mouse wheel let me think it is problably something more specific that a RAM issue. I did some cleanup, without success. The system is fanless and thus quite stable and remains clean. I reseated the RAM. No change. I run memtest86+. No errors. > I must restart X to get it back. This sounds like a Xorg drivers problem, but if Xorg has partially crashed due to RAM or power problems, then this cursor problem will go away after you address the hardware issue. Scrolling with scrollbars or arrow keys works. Scrolling with wheels in others apps like terminals works too. No useful message in syslog, dmesg or console. What does /var/log/Xorg.0.log reveal? Nothing either. In the meantime I found another application triggering the problem (some image display software), so this is not specific to Gecko. -- Hervé

[gentoo-user] Mouse wheel makes firefox hang
Hello, After a recent system update I get this annoying strange behavior: when scrolling in a firefox or thunderbird window with the mouse wheel, the full X interface freezes for some seconds, then a system beep is emitted and the interface unfreezes, but most of the time the mouse cursor becomes invisible. I must restart X to get it back. Scrolling with scrollbars or arrow keys works. Scrolling with wheels in others apps like terminals works too. No useful message in syslog, dmesg or console. I tried various things, like downgrading firefox and thunderbird to the version I used before the upgrade, compiling without the system-libXX use flags, downgrading the nvidia drivers, upgrading the kernel, etc... without success. Any idea ? -- Hervé
