  • 1. G3 HD Crash Restore and Recover
    I have had a major HD crash on my Mac G3 (64 Meg Ram, 1.6 GB HD, System 8.6) with which I need help. I would like to restore the hard drive completely or if not that at least get the data from it. I did have a good bit of it backed up but some of the more recent information was not, there are some crucial files I need to recover. The disk icon does not appear on the desktop. I have used both Norton and Disk First Aid to no avail so far. DFA says the volume could not be mounted and it cannot fix the problem. Norton (4.0.3) Disk Doctor works for a while and fixes a couple of issues, then says it has encountered an unexpected problem and cannot continue (error found: 23008). Unerase only found 41 files when I used the custom search option "search entire disk for parts of the catalog tree," otherwise it found nothing. When I used a text search it found some files but they only appeared as "text file #1, #2," etc. These files are jumbled and not very usable for me. The disk does not show up on the list of disks when I try to use Volume Recover. I am not very experienced in these things beyond trying the steps mentioned above. Any help is greatly appreciated, thanks in advance. Joe
  • 2. PC100 memory on a PC133 bus
    I have a G4/667 tower (Digital Audio series) with 1 GB of RAM (as two 256 MB modules and one 512). On running some routine diagnostics today, I noticed (after all this time) that the 512 MB module is PC100 memory and the other two are PC133. I know this model is rated to take take PC133. Having this PC100 module installed makes all of them run as presumably slower PC100 memory. My question is: For most typical-duty purposes, am I really that likely to see a noticeable performance improvement by replacing the 512 MB module with PC133 and allowing all of the memory to operate as PC133? My hunch is that I wouldn't usually see a significant performance improvement though there might be specific types of computing where I might (memory-intensive apps that don't have a high cache hit rate, for example). But that, admittedly, is just a hunch.

    Just bought this card and placed in my old G4 agp instead of the Rage card. The first time I click on a harddisk icon the window opens in two jumps - the second time I click on the same hd icon it opens much more smoothly. Why is that? TIA otn
  • 4. Connecting to OS 8.1 from OS X
    At work we have a benchtop Mac running OS 8.1 connected to lab equipment. Other scientists from remote locations have been linking to this Mac from OS X but now the company has shut off Appletalk at that remote location and now the OS X guys can't see the 8.1 Mac. We may be able to upgrade the lab Mac to OS 8.6, anything higher than that and there's compatibility issues with the benchtop software. Does 8.6 have the ability to allow users to connect through TCP/IP or was that not until OS 9? If we can't upgrade from 8.1 I may just install some old FTP software on the lab Mac. Unless anyone has any other suggestions?
  • 5. Stuffit Expander launch failure
    I picked up a shiny new iBook today, did a format and reinstall, then ran all software updates. After that, I started downloading apps to install. The first time I attempted to launch Stuffit Expander, it hung. Nothing logged, no crash report. I performed the obligatory troubleshooting steps of repairing permissions and installing the latest version of Stuffit Expander. No change. Then I noticed that no stuffit preference files were present. I scp'd com.stuffit.Engine.plist and com.stuffit.Expander.plist from my work Mac to the laptop--and was then able to lauch Stuffit Expander normally. Both machines run 10.3.7. I couldn't find anyone reporting similar issues. Has anyone else seen this? Any ideas what caused it? -- Jennifer Mullen XXXX@XXXXX.COM

problem with X11

Postby george » Sat, 18 Aug 2007 12:18:59 GMT

I have installed X11 on my mac book pro and it seems working.
I have added the following in my .bash_profile

# if we're NOT ssh'd in
if [ ! ${SSH_TTY} ]; then
# make sure X is running
if [ "`ps -x | awk '{print $5}' | grep X11`" = "" ]; then
open /Applications/Utilities/X11.app &
# then refocus Terminal.app
osascript -e 'tell application "Terminal" to activate'
fi
# if DISPLAY isn't set
if [ x${DISPLAY} = x ]; then
export DISPLAY=:0
fi
fi


and the following in .xinitrc

quartz-wm

so as to call X11 applications directly from my terminal.
It works, bot few hours, but then at some point, when I use some
application that requires X11 just stop working!!!!!
It returns me the following error message

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: :0

What does it mean ans how is possible?!?!

Isn't it a lot cleaner and simpler to use /usr/bin/open-x11 ?

1.Problem with X11 application rendering to screen.

I have an X11 application whose graphical display fails to render to
the screen for some reason.

The error I get is:

Xlib:  extension "XFree86-VidModeExtension" missing on display "/tmp/
launch-4gaNW3/org.x:0".
Xlib:  extension "RANDR" missing on display "/tmp/launch-4gaNW3/org.x:
0".
Xlib:  extension "XFree86-VidModeExtension" missing on display "/tmp/
launch-4gaNW3/org.x:0".

Any idea what this error means at all?

2.Still have problems with X11

Hi,

I am running 10.5.5.

I have a problem with X11 not starting.

Dave Seaman (on this NG) started to help me but I restarted and it 
worked.  The last thing he suggested was that I rename my ~/.xinitrc 
until I diagnose the problem, but I don't have a ~/.xinitrc file.

What can my problem be?

3.Problem With X11 Install

I'm running Tiger on an IBook.

I have the X11 Package.  When I try to install it, I get the msg.
"Can't install X11 on this volume.  Newer software is already installed
on this computer."

I can't find an installed X11 program.  I would appreciate suggestions
on how to find this "newer software" or on how to overcome this
roadblock.

Thanks.

4.Matlab X11 windows don't work on mac if X11 is

It's great to hear a voice from "the inside"! It means a lot to me
that some one at TMW feels the same.

Had there been much progress before the intel-mac issue? I mean what
was the rate of "Macification" like before then? As it currently
stands, I don't plan on using Matlab except for situations where I
really have to - if the program was more OSX friendly (and integrated
with the OS better) I would actually use it much more. I am planning
to go into post-grad research in areas where I could make use of
various Matlab toolboxes. As it currently stands, I don't think I can
really do that - Matlab is too irritating compared to just writing
various things myself. I'm serious about this - TMW are cutting
themselves out of a lot of more hardcore users, and the number of
technical people moving to macs is rising, rapidly. In my
engineering/computer science course, more then 10% of the people that
I know personally have switched to macs/OSX during the degree. These
people are generally (huge generalisation here, but anyway) the ones
who are going to be doing research, and ending up in teaching or in
positions of authority. I would've thought that TMW would like to
encourage these people to use Matlab rather then make it a painful
experience.

5.Matlab X11 windows don't work on mac if X11 is already in use

I have just realised that if I already have an X11 window open (in
this case, IDL), starting Simulink on my iBook causes all the
Simulink windows to load in monochrome, making them unusable. As in
you can't see anything on your models. When I closed the IDL session
and reloaded Simulink, things went as they should (actually some
colours were corrupted and some menus had rendering errors, but I was
able to actually use the program).

I just shelled out for this program, and my overall impression of the
OSX version of Matlab is pretty damning - I don't mind if it's ugly
but the functionality in terms of some basic mac UI stuff is just
terrible.

E.G. When I load up Matlab, it seems to think I will want to open a
file from inside my Matlab folder. How about looking in my home
directory to begin with, Matlab? Combined with the 1995 method for
directory navigation, this means that opening what I was last working
on is a 30 second task. I haven't used any software in about 5 years
that was this annoying in terms of basic open/save/print
functionality.

Sorry, I think I just turned my question/observation into a rant. I
have just never paid for software that was so sub par in it's UI. Am
I the only one who feels like this?

Just to add another dimension to my first post here, what's the go
with upgrading? I bought r2006a a few days before r2006b came out.
Can I get an upgrade, or do I have to buy it outright? Please tell me
I don't have to buy it outright....
