Re: [gentoo-user] Nice level for X11
You really don't know what I was talking about. (sorry for my bad English). I'm NOT running my X11 session as root (only X server), but as normal user. Setting the nice level of X server below 0 (for example -10 or -15) made all X11 clients (the graphical programs) response faster. Everything responses smoother. This is not about RUNNING faster, but along with my preemptible kernel my whole X11 session become smoother. (this is important for me because I own a very slow computer..sh*t sempron processor..). Not ages ago (sarge or sid in 2006 for example) Debian asked me if I want X server to run with higher priority. (when installing x11 package with debconf set to low). This gave me the idea. My X11 session works good. There was 2 system hangups while playing video with Mplayer. Maybe that was because of the very high priority. I will play with the values, -15 proved to be dangerous. 2008/5/14 Josh Cepek [EMAIL PROTECTED]: Abraham Gyorgy wrote: Well I did a little Google'ing, and i found a blog. There the author wrote: lapitopi gyuszk # snice -15 X As already pointed out, running process with a nice value less than 0 can only be done by root, and it's usually a really bad idea to run your entire X session as root. X (and applications running under X) involve a lot of code, and vulnerabilities can exist in this code. You don't want any vulnerabilities to be potentially exploited as the root user. Take the multiple X-terminal vulnerabilities reported last week by the Gentoo security team that could allow local attackers to hijack X11 terminals of other users. The moral is don't run as root unless you actually need to (and I'd argue that you should never need to run X sessions as root.) After doing this, I ran htop and it told me that my X11 was running with -15 niceness. I experience better responsiblity under all of X11 (kde, firefox, konsole, anything). For example switching from an existing Firefox window to (for ex.) Konsole or Xchat is much faster. I have to add, I own a very slow computer, so I have to do everything to speed up my system. It is very slow even with WinXP+official drivers. If the goal is to lower the priority of other tasks the computer may be doing at the same time, perhaps setting a higher nice value for them would offer similar results. In the case of compiling, portage provides an easy way to lower the priority with the PORTAGE_NICENESS value. 2008/5/14 Uwe Thiem [EMAIL PROTECTED] mailto:[EMAIL PROTECTED]: On Tuesday 13 May 2008, Andrey Falko wrote: On Tue, May 13, 2008 at 4:02 PM, Uwe Thiem [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: On Tuesday 13 May 2008, Abraham Gyorgy wrote: Hello guys, in which configuration file can I set a nice level for X11?

Most likely, you don't want your system to crash when coming back up when power fails soon after it is restored: your system could be in the middle of a fsck. Generally, you want enough capacity to: power off, power on, and then power off safely. I second this. If the system is busy, it might take a couple of minutes before it really shuts down. Ten to fifteen minutes is the MINIMUM runtime I'd suggest. As the battery ages, runtime will lessen, plus it gives you more room to expand. Power usage does not scale linearly, if 200 watt usage lasts X amount of time, 400 watt usage lasts less than X/2 and 100 watt is more than 2X. My personal experiences with power outages is that they're rare and short, but when they do occur they happen a few times during the day/night. This, of course, may vary from your area. Another thing to consider is brownouts or volt dropages. The ups will kick in if the volt level drops too low (or too high). If this happens frequently enough, it will deplete the battery or wear it out much more quickly. I am very happy with the CyberPower Intelligent LCD Series: CP*AVRLCD http://www.cyberpowersystems.com/ The series has: NUT support: You want something that works with NUT. Instead of a vendor specific package. This way your acquired skills are portable and future proofed. Network UPS Tools http://eu1.networkupstools.org NUT is great. It safely powers off my system when the UPS is low. Additionally, I set it up to e-mail my cell phone when the power state changes. If I go out during a power outage, I can stay out longer if I know the power is not restored. My personal experience has been with APC equipment, but CyberPower is also a great maker. I also second NUT. It's a better, more flexible framework that supports just about any decent ups. USB interface: * A USB port is more future proof: serial ports are becoming rare. * Allows monitoring UPS state. * Allows powering off the UPS. USB is almost mandatory now. Serial ports are usually only on high-end expensive models, and (almost) never on what you'll find in stores. LCD Display: At a touch know: * power consumption (don't need to pull out a Kill-O-Watt) * battery charge * estimated minutes remaining Before spending extra on anything with an LCD, google the model or lcd errors first. I've seen reports that they tend to be inaccurate, especially with APC. Mine under reports watt usage by a significant amount, somewhere between 1/3 to 2/3 of actual usage(I forget what my tests with various light bulbs showed). This was testing the ups with only a small lamp plugged in, everything else UNPLUGGED (not just off). I also used several light bulbs since they can vary a little. One thing to be wary of is like most inexpensive UPSes it does not provide a pure sine wave. This can damage a power supply that has active power factor correction. Luckily for my Silencer 750 Quad according to the manufacturer due to the short time in which the UPS is in use it is not an issue. -Arthur PaulNM -- gentoo-user@lists.gentoo.org mailing list Thanks for your exhaustive replies. I've decided to go for the APC ES-350 for seventy bucks at the local Staples. Mostly because I could pack it home on my bike and avoid the shipping charges which are huge for heavy things, like UPS systems. According to the table on the back of the box I get 6min with a 15in LCD monitor, so I should get slightly more with no monitor attached. I don't care if I don't save something or have to abort a compile in mid-stream. What I'm afraid of his having the power cut out while the r/w head of the hard drive is in motion. That can't be good. -mw -- gentoo-user@lists.gentoo.org mailing list

I have found that (the current version of) CFQ is better than others. Please, correct me if I'm wrong. I believe you're mixing the block device I/O SCHEDULERS (CFQ, deadline, anticipatory) with the process scheduling PLOCIES (Real time, BATCH, FIFO...). While the first are used to reorder the I/O requests to optimise the head movements in HDDs, the latter define how the kernel should divide the CPU time between processes and their threads. Choosing one I/O scheduler over another may have some effect on the way the X sessions behaves, but it would be indirect. Choosing one scheduling policy over another for a given application has a direct impact on its performance. As a matter of interest, I remember reading somewhere that squeezing 1000Hz out of an old machine may have the opposite effect to that intended. Is this pub talk, or have you experienced something that confirms this? There's a logic behind this claim. The timer frequency (as I understand it) defines how many times per second a process can be interrupted (making the CPU work on something else). The higher the frequency, the smoother the experience, but at the cost of the time it takes a process to finish. Let's see what happens if for example you had a massive tar job (e.g. archiving your $HOME) and wanted to use the system as usual at the same time. Case 1 - timer freq. = 1000Hz Working with the system is (almost) as normal - fast responses, no delay in switching windows and so on. Tar finishes its job for 30min. Case 2 - timer freq. = 100Hz The system is almost unusable. Switching windows takes several (tens of) seconds, responses are extremely slow. The tar job is done after 10min. So, too many interrupts in a saturated system (or slow CPU) would make the CPU work a little on each job and start another w/o finishing anything in time.
