Hey,everyone! I've got Ubuntu 10.10 , when loading I see the following message:
"atk: Resources not safely usable due to acpi_enforce_resources kernel parameter"
What does it mean and do I need to fix it?
i have 2 front ends that receive traffic (http server) and should run some scripts in crontab, some of the scripts should just being running by 1 server at a time (active one) and others should run on both. Regarding the http like is load-sharing i think i cant use heartbeat, right? heartbeat is just for active-stanby or can we use to a active-active as watchdog? i have a cisco css to load sharing the http, and i can make a watchdog script to the apache. Regarding the cron crontrol i was thinking to make a script that replaces the crontab file to whatever is the correct one.
When the heartbeat start what parameter is sent to the script that are resources? a start if active node and nothing if is the standby?allways start?how should i config the haresources to do it? what is the best way? i have other situation that is making a nfs server in solaris 10, i have 2 servers with shared disks ( sun array), can i use heartbeat to this too? it is possible to make it in such way that if i had i failover in nfs server the clients doesn't need to reconnect?
I have not dug into Ubuntu for almost a year now (Since Jaunty, really). I am trying to come to grips with Grub2, but have just now encountered it in Lucid. I am having a terrible time with the graphics chipset, and it may well be that Ubuntu cannot be used on this computer (an older laptop with the dreaded Intel 82845G graphics chip). There are a number of older bug reports that it is unsupported, but some success in more recent versions.
Anyway, one suggestion has been to add i915.nomodset=1 to the kernel boot line. Now, this was a cinch in Legacy Grub, but I have been reading Grub2 wikis and tutorials for two days now, and I know about the config files, but I cannot find anything which tells me specifically how to add a parameter to the kernel boot line.
i m using following kernal.
Code:
# uname -r
2.6.18-128.2.1.4.9.el5xen
According to security manual i need to incorporate following changes into kernal parameter but i m not sure when and how these changes will be implemented.
Code:
net.ipv4.conf.all.accept_source_route must be set to "0"
net.ipv4.ip_forward must be set to "0" (zero)
icmp_echo_ignore_broadcasts must be set to "1"
net.ipv4.tcp_syncookies must be set to "1"

I recently enabled noapic on my laptop because it was experiencing strange input freezes on several distros that I tried.Ok, so it does not use the ioapics. My question is, what does this mean for the system? If it used apics before, what happens now? I am a freshly graduated computer science major, and I have worked with basics pics on projects before, but I am curious how this effects the running system.

View 5 Replies View RelatedIt's documented in the howto's that you need to have the nomodeset kernel parameter specified if you want to run the proprietary Nvidia driver. But I read in certain posts that this is only required for "older" graphics cards.Can someone shed some light on this? Is the parameter ALWAYS required when running the nvidia driver, or only for certain graphic cards?
View 9 Replies View RelatedI've done the usual edit of /etc/sysctl.conf to include the parameter, but it just tosses errors. I haven't had to tune a kernel in a very long time, what's different about it nowadays (or have I simply forgotten how)?
edit: Added "kernel.semmni = 2048" to the tail of /etc/sysctl.conf and then ran "sysctl -p". End result is an unknown key error (apparently kernel.semmni isn't the valid name anymore?).
I am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

Hoping for some verification before I proceed.An alt kernel was installed side by side with the current mainstream kernel during an experimental NIC driver install. Unfortunately, since the experiment failed I would now like to remove all traces of the alt kernel since it was given a version ahead of the current main version and I would like to avoid all possibilities of contention should a future kernel upgrade use the experimental alt kernel's version number.

I'm looking for an app that will provide a large (full screen and clear) display countdown clock, basically so I can use my laptop in public to show how much time remains in a basketball quarter. I'm the official timer.If it counts up like in soccer rather than down, that's fine too. If the app can also show the score, that would be great, but it is not a requirement. We don't use a shot clock, so that is not required either.

View 6 Replies View RelatedI am new to linux, am attempting to abandon microsoft because after 30 years I have had enough of being jerked around by them. I have used yast to install the components of Postgresql and pgAccess, including language support for Tcl/Tk. Starting the postgresql server is successful.
I would like to use pgAccess as a front end to the server/databases. However, nothing I do seems to make pgAccess available. I can't invoke it and can't find it on a menu anywhere. In searching forums on this issue they all discuss compiling postgresql and pgAccess on the local machine, no one talks about how to use pgaccess whose installation was managed by a gui. Do I need to start over, removing everything I installed with yast, and go with the command line installs and compiles, or can I use what yast installed?

I have F14 x86_64 installation on my laptop. I once used latex vary well. After recent update of the system, there seems to be a latex font problem. When I ran xdvi, the dvi window flashed once and disappeared immediately.
The error in the terminal is:
Code:
$ xdvi ms
Warning: Missing charsets in String to FontSet conversion
Warning: Unable to load any usable fontset
Error: Aborting: no fontset found
I have xorg-x11-font-utils, xorg-x11-fonts-misc, xorg-x11-fonts-ISO8859-1-75dpi, and xorg-x11-fonts-ISO8859-1-100dpi installed. I then ran:
Code:
# yum install xorg-x11-fonts-ISO8859*
to install some extra fonts. But the problem remained. What shall I do?
I'm in the process of trying to install FC14 64 bit to my Window 7 64 bit system. This new system has a 6.0 Gb/s internal hard drive.When I reboot with the F14 install disk I have made it past the disk verification (is Verified) and then picking a language but then I get the message "No usable disks have been found". In Win 7, the Disk Management window shows that 184 GB of space are free. Is there some disk preparation that I should do to make this space available?
