Odd behaviour in OO - Java??
by Peter Alcibiades 01 Nov '06

01 Nov '06

Just changed to Etch AMD64, and OO behaves oddly, I suspect connected to Java in some way. The approved way of putting buttons and controls into your documents is VIEW>TOOLBARS>FORMCONTROLS. This brings up the little click and paste widget, and it does allow you to paste buttons in. Having done this, the next step would be right click on the button. You are now supposed to be able to choose CONTROL. However, nothing happens. The cross hairs stay in place, and all I can do is create a new button. In Writer, drag and drop doesn't work at all. Select some text and try to drag it, and nothing happens. Base seems to be so unstable as to be unusable. Almost anything you do crashes it. Suspecting this might be something to do with Java, I tried to install both the Sun JRE 64bit and 32 bit versions in addition to the FSF one. They appeared to go in fine, but the only one OO is aware of in the OPTONS>Java menu is the FSF one. How does OO become aware of a JRE? You're invited to supply classes and so on, but I can't figure out how to do that because of not being able to find anything it will agree is a Jre. Where would I look for such a thing? One thing that suggests it may not be Java, its very odd that if it is Java, my Mandriva installation shows no Jre at all, but all this stuff works fine. On the other hand, turning off the FSF Jre in Etch leads to a lot of stuff going missing. Its true that Mandriva 2006 being stuck in a timewarp with OO, I downloaded and installed it direct from OO. The Mandriva is 2.03 and the Debian is 2.04. But its hardly credible that going from 03 to 04 screwed up something as basic as this. Anyone have any ideas? Should I just apt-get uninstall and then download and install directly from OO? Or does anyone know some way of testing that the Sun Javas are installed and working and telling OO they are there?

System shutting itself down but I can't see why
by cl＠isbd.net 01 Nov '06

01 Nov '06

My Slackware 11 keeps shutting itself down but I can't see why. In /var/log/syslog and /var/log/messages there are messages from apache and samba saying they're shutting themselves down because they've been told to but I can't see a reason anywhere. It happens fairly randomly anywhere from once every ten minutes to once every several hours. It reboots all by itself and continues running. It's not a temperature problem as the system is way below the BIOS alarm temperatures. Any ideas as to how to diagnose this or places to look? -- Chris Green (chris(a)halon.org.uk)

My random resets solved - I think
by cl＠isbd.net 31 Oct '06

31 Oct '06

I think I have found the cause of my random system resets, nothing at all to do with software, there was a whisker of solder or something similar adjacent to the little PCB which has the reset button on it and it occasionally reset - probably with thermal cylcing or whatever. I found it because the reset button wasn't working and, getting it to work, I found that wiggling the board caused a reset. Humph! There I was thinking it was some wierd option I'd set when building my kernel! :-) -- Chris Green (chris(a)halon.org.uk)

Monitoring mains via serial port
by Ted.Harding＠nessie.mcc.ac.uk 31 Oct '06

31 Oct '06

Hi Folks, Your expertise and wisdom may help me clarify thoughts on the following. I'm contemplating buying a couple of UPS units, at the very cheap end, so no comms to the computer which could be used to initiate a programmed shutdown if the mains goes off. So in turn I'm contemplating rigging a little circuit which would supply a signal to a serial port while the mains was on. The germ of the idea is to use one of those very cheap power converters which can deliver a DC voltage chosen from (say) 3V, 4.5V, 6V, 9V, 12V, and set it up so as to put say 12V between 2 pins on a serial port, when plugged directly into the mains. Then it would be easy to have a little script running in the background which would monitor the lines on the serial port, and initiate a shutdown if the voltage dropped to zero for (say) more than a minute. That's the bare bones of the idea, and indeed enough to define a basic soldering-iron job! But I'm not sure I'm being circumspect enough here, so would welcome comment! With thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 31-Oct-06 Time: 20:26:50 ------------------------------ XFMail ------------------------------

matrox G450 dual head and two identical monitors problem
by Jenny Hopkins 31 Oct '06

31 Oct '06

Hullo there, I've got a Matrox G450 dual head graphics card. I've then got two identical monitors: Flatron L1715S. In my xorg.conf I've put the vertical and horizontal refresh rates as the same, however the second monitor stays dark. If I tweak the horiz rate for second monitor, the screen appears, but fuzzy. (I've posted what I think ought to work but is out of range below. If I change the HorizSync for Monitor[1] to 30-63 it does the fuzzy thing.) Can anybody see any earthly reason why the same setting is not valid? Thanks, Jenny Section "Monitor" HorizSync 30-83 Identifier "Monitor[0]" ModelName "LG" Option "DPMS" VendorName "Flatron" VertRefresh 56-75 UseModes "Modes[0]" EndSection Section "Monitor" HorizSync 30-83 Identifier "Monitor[1]" ModelName "LG" Option "DPMS" VendorName "Flatron" VertRefresh 56-75 UseModes "Modes[1]" EndSection

Simple apache/hosting question
by cl＠isbd.net 30 Oct '06

30 Oct '06

Well I assume it's simple but I can't quite see how to sort it out. I'm running Slackware 11 on my home machine and, on the home network, its IP address is 192.168.1.1, it's running apache 1.3.37 (the Slackware 11 default). I have set up my router/firewall so that HTTP requests are sent to 192.168.1.1. At just-the-name I have the domain isbd.ltd.uk set up so that HTTP requests are routed to my static IP address at my ISP. So far, so good, if you go to http://www.isbd.ltd.uk/ up pops the default apache index.html page to indicate that it's all working. However, if I go to http://www.isbd.ltd.uk/~chris then instead of bringing up the index.html that I have in the public_html directory in my home directory on the Slackware system I get an error:- Firefox can't find the server at server.isbd.ltd.uk. ... and Firefox is looking for http://server.isbd.ltd.uk/~chris/ which of course doesn't work because server.isbd.ltd.uk doesn't exist in the outside world. How do I get my Slackware machine to look like isbd.ltd.uk when seen from the outside world but give it the name server and/or server.isbd.ltd.uk internally to my home network? -- Chris Green (chris(a)halon.org.uk)

kernel build options (make menuconfig) for Core 2 Duo processor
by cl＠isbd.net 27 Oct '06

27 Oct '06

Can anyone tell me where I can find (or just tell me) the best 'make menuconfig' options for a Core 2 Duo 6600 processor. I can work out most of what I want but there are some grey areas. These are the settings I have at the moment:- [*] Symmetric multi-processing support Subarchitecture Type (PC-compatible) ---> Processor family (Pentium-4/Celeron(P4-based)/Pentium-4 M/Xeon) [*] Generic 86 support [*] HPET Timer Support (2) Maximum number of CPUs (2-255) [*] SMT (Hyperthreading) scheduler support [*] Multi-core scheduler support Preemption Model (No Forced Preemption (Server)) ---> [*] Preempt The Big Kernel Lock ... (the rest seem pretty straightforward) My main question is whether I have the processor type set correctly? Should it be Opteron/Athlon64/Hammer/K8 rather than what I have selected as the Core 2 Duo, although it's an Intel processor, has some of the AMD-64 optimisations I believe. Or maybe I should select soemthing else completely. A supplementary question is whether to set the "Maximum number of CPUs" to 4 rather than 2 since Hyperthreading is enabled. I will eventually come to the end of all these questions relating to my new system! :-) It's very nearly there now, I have Slackware 11 up and running well on it and vmware installed with a Windows XP guest. Once I get these final bits of tuning done I'll disappear back into the woodwork. -- Chris Green (chris(a)halon.org.uk)

Mouse help still needed - Xorg setup
by cl＠isbd.net 25 Oct '06

25 Oct '06

I can find very little help regarding the "InputDevice" section of xorg.conf. I have tried various "recommended for Logitech" setups but I can't make any sense of how the mouse works after trying them. There seems no logical connection between the options I set and the resulting way the mouse works. I have now got a rally minimal InputDevice section:- Section "InputDevice" Identifier "Mouse1" Driver "mouse" Option "Protocol" "Auto" # Auto detect Option "Device" "/dev/mouse" # Option "ZAxisMapping" "4 5 6 7" # Option "Emulate3Buttons" EndSection This results with the left button being button 1, the right button being button 3 and pressing both being button 2 (so in spite of commenting out Emulate3Buttons it still does! Then I have the two mini-buttons which are button 8 and button 9, how can I use those? What I actually want is buttons 1 and 3 as above, one of the little buttons as button 2 (middle/paste) and the other little button ideally as a double click of button 1. Where can I find out what all the options like "CorePointer", "Buttons", "Protocol", "ZAxisMapping" and so on actually do? -- Chris Green (chris(a)halon.org.uk)
