Re: /dev/modem deleted at boot time
November 24, 2009 by hcvv
Glad it works! Had to read a bit in the man page of udev and to look at a link I had saved earlier: Writing udev rules. I had to test a bit. First I had to find a system with COM ports 
All the test tools mentioned in the link did not really help. A real reboot was needed.
BTW, my name is not Sir, but Henk.
Re: /dev/modem deleted at boot time

Hello Myrlin,
I did the following:
su -
Password:
cd /etc/udev/rules.d
echo 'KERNEL=="ttyS0", SYMLINK+="modem"' >10-local.rules
exit
What does this do (so you can do this in your favorite way)?
1) become root;
2) goto the udev rules directory;
3) make a new file 10-local.rules with one line
KERNEL=="ttyS0", SYMLINK+="modem"
As you may have guessed this tells udev to generate a symbolic link with name /dev/modem, pointing to /dev/ttyS0. It will do so on boot, so reboot and check if I told you something useful.
When this works, keep a copy of what you did somewhere else (preferable not on your root partition) so you can redo after a (re)install/update.
Re: /dev/modem deleted at boot time

OK, I see the modem0 vs. modem problem.
When I read your post, my impression is that you still think that your link can survive a boot. This defenitly NOT the case. As I explained, the whole /dev is created fresh at boot. As /dev is nowadays a special file system that resides in memory, it is impossible that anything put in there will survive a system halt/reboot. So stop trying there.
The solution is in an udev rule. They are invented for the filling of /dev at boot and also later when the kernel signals the udevd that hardware is connected/removed. The only problem is that I have ATM not enough knowledge how to do this. Maybe I have more time tomorrow. But as reading udev docs can also be done by you, I gave you these hints to set you on the correct path to fullfillment

Hello Myrlin,
Back from a stroll (yes, there was some sun, we have some rain, some wind also, but nothing compared with what I see from the nws in the UK).
As imho /dev/.modem is not an exceptional thing to have and seeing your explanation about what you want, I started YaST > Networking > Modems. It detected no modem (very good, because I do not have one), but gave me the opportunety to create one, When I click this the firsts thing it suggests is to us /dev/modem for it! I did not cary on, but did you try this? I suppose that when YaST configures something here, it will at leasst see that /dev/modem is there at every boot.

This might be of little comfort to you, but nowadays /dev is created anew at every boot by udev. That means indeed that every change you make there is only valid as long as the system lives.
I think the official cure is to add a rule to the udev rules. They are in /etc/udev/rules.d.
You next question will be: "How do I do that?" (am I clairvoyant or not 
).
Here I am at about the same position as you. I just opened the man page of udev and started reading. You may do likewise. And googling might help also. But my wife calls me to go out for s stroll in the sun. So maybe you will find it first.
Re: no gui at boot
November 22, 2009 by hcvv
And a comment to the mentioning of runlevel in menu.lst.
This is NOT complete bogus. one can give the runlevel as a parameter to the kernel at boot time. the kernel will give this value to init when it starts init. It will be used instead of the default value in /etc/inittab.
Thus one can
1) add the runlevel to the boot parameter line in the grub screen;
2) add it to a boot parameter entry in menu.lst.
The first case is of course only for test/problem searching boots (booting runlevel 1 e.g. when not root partitions must be repaired).
I see no direct use for case 2. It will at every boot overrule the default in inttab, thus only obfuscating things.
Re: no gui at boot
November 22, 2009 by hcvv
I jumped into this thread when there were already a lot of posts. I am not going to tell into detail what I thought I read in what post, but my conclusion was that the suggestions to resolve this where of several different kind and usefulness. I wanted to point to one wrong way (the runlevel in menu.lst) and to throw in my suggestion to check /etc/inittab instead. I added the remark that I had NOT read all of the post thouroughly, to appologize in advance for it, because maybe I had missed something and accordingly was talking nonsense.
At that moment I still had the idea that "no boot to the GUI" was one of those often found and solved in the openSUSE Forums, thus I pointed to them, because I am not willing to repeate solutions to be found there easily.
When houndhen reported runlevel 2 as deafult, the case was clear (it NOT being one of those to be found in the openSUSE forums). That means it was clear as how to repair it. But it is a complete mystery to me how a default runlevel of 2 can be in inittab right after an install. This means running without GUI and even without network! A normal install would put there 5 and a text only install 3, but 2?
And as extra information to houndhen. The tool telinit is to tel init to reread its configuration. That is for live changes to /etc/inittab to become active. For more information (as for more information about most badic Unix/Linux tools and configuration files) read the man page
man telinit
man inittab
In this case telinit is of no use because the default runlevel is only used at system startup.
Re: no gui at boot
November 21, 2009 by hcvv
Please houndhen, did you read my post or not?
It tells you what the entry should be. When it is 2 in your case that is utterly fault. How can such a thing happen? It is no normal runlevel. 3 and 5 being the normal ones. Change it to 5 and reboot. Forget about the telinit, that story is to long to explain now.
Re: no gui at boot
November 21, 2009 by hcvv
Did not read all of the (sometimes contradictory) text above.
The fact that runlevel 5 is the default is NOT configured in in GRUB, but in /etc/inittab:
# The default runlevel is defined here
id:5:initdefault:
To shutdown thee system from the console read the man pages for dhutdown, halt and reboot. (and may be init).
In http://forums.opensuse.org/ there are myriads of cases having the "no GUI after boot" problem. Look there for the 11.2 ones. Mostly the running of sax will help.

Only lunches and refreshments. But it looks rather serious.

Did you know the forum is not only poluted with dutch from the Belgian, Dutch and South African members, but also by ads? I will try to translate:

Nice price for a notebook.

Re: Forum topics not easily readable

Hehe!. My ISP filters spam for me and is rather good at it. From time to time I check what they put in my spam-box and empty it.
I just checked and found a mail from 11 september telling me to read posts on this forum. Apparently the first one of those was caught in the act, as I suspected in my post above. Two later mails were not accused of being spam. Don't know why.
But I suspect tthat such a never before used address (and not from Lefora) is on nobody's green list.
Re: Forum topics not easily readable
September 20, 2009 by hcvv
Thanks. The facts being that I subscribed to mails long ago. I made a special inbox for them in Kmail and a filter to put mails coming from lefora there. Also a long time ago (somewhat less long then the one above), mails stopped comming. I did not bother to much, because I am rather up to date using the RSS feeds.
And now since about two days these mails are comming in. They are not comming from a lefora host, but from forum@forumnotification.com (be glad that such a nothing saying name was not filtered out by any spam filter).
They do not inform me that a new post was added to a thread I contibuted to, but tell me I did not read some posts (naughty boy), which is not true.
Another remark about the mails themselves. They are HTML formatted. Which Kmail does not render to begin with (security, security!). I consider it being a bad example using HTML coded emails. (But I am an old grumbler 
).
Re: Forum topics not easily readable

It is quite readable for me now. Black on Yellow is a "Best combination" in my list. 
But I do get e-mails now from something that supposes I am not reading the posts. Which is not true. I do read them, because they are signaled in my RSS feeds in Akregator. But I do not always log in then when I do not wish to add a new post to the thread.
Re: Forum topics not easily readable

There are still some difficult to read combinations, like the blue on black of the names and number of posts. Also there was something white on yellow on the login screen (do not know what it said, could not read it).
Also the fact that hovering over a text is brightening it does not attract new users IMHO. When I come to a site and have difficulties in reading it, I am not going to hover everywhere in the hope that will better it. No, I go elsewhere.
I once (long ago) studied this subject a bit further using a set of three papers by Gerald Munch printed in 1984 in three Volumes of "Tekniques" (from Textronix, Inc). It contains a chart of Best/Worst Color Combinations (Jo Ann Kinney 1962). As computers improved a lot since those times, but man did not, I suppose they are still valid.
Amongst the worst combinations I find:
. Yellow on White and vv.
. Blue on Black
It is not a trivial subject.
Re: Poll: How often do you change your desktop?
September 9, 2009 by hcvv
Almost never. I made a clean environment with two desktops with two very different wallpapers. I think the last change was about two years ago when I changed one of the wallpapers.
And as a reinstall/update (to a next openSUSE level) should give continuity at the first place, it would be the worst time to change the desktop. The update first has two prove that it can behave the same as before!
Re: I'm looking forward to Opensuse 11.2
August 19, 2009 by hcvv
Not particular "looking forward". I am happy with 10.3 and KDE 3.5. I am for stability, not for eye-candy.
I am also afraid that my wife and two other friends which I lured into using openSUSE will not be happy when they have to adopt to a new environment, and that only for security reasons.
Security reasons because 10.3 will have half a year shorter lifetime now and thus no security updates shortly after 11.2 will be there. So you may come to the conclusion that I am very unhappy with the shortened openSUSE lifetime. For one of the systems I have to travel rather far to update it.
I know that openSUSE is a coal for many of us (that confirms that it is not mature as an alternative to Windows, but a hobby), but it is a means to get you work done for others (as a better alternative to Windows).

That sounds good, but as we have no bias, we are as wise as before. You seem to use a sort of English as your base for "Li (as in lint)- nicks (as in nicks)". But as there is considerable difference between English and American (and inside those two emanations of those languages), we, non native speakers of any those, do still not know anything now. How do we know how an English/American speaker pronounces the Finnish name Linus? (mostly lousy from the Finish point of view).
When talking about pronounciation you should use IPA . Nice, a new language to learn!
