* Problems with Brltty @ John J. Boyer ` Nicolas Pitre 0 siblings, 1 reply; 18+ messages in thread From: John J. Boyer @ UTC (permalink / raw) To: blinux-list hello, I have just installed Redhat 7.1 on my second hard drive, with brltty and no speech. When the boot process starts I quickly get a message saying "redhat something". then amother message and another that go by too fast to read. Then the message "looking for new hardware", then two dot 6's and the letters a and t. If I type a letter on the computer keyboard, the login message may come up. But sometimes I have to press the advance bars to find it. The Braille display doesn't seem to be tracking the line where the cursor is, though it does show dots 78 for the cursor. If I do something like ls I usually have to press the same end of the same advance bar twice to get the display to move. And it is beeping frequently. Any help would be appreciated. I really can't do much with my new Linux until brltty behaves consistently. Thanks.

Robinson @ UTC (permalink / raw) To: blinux-list; +Cc: support I think turning kudzu off is a bad idea, especially for inexperienced users. Undesirable behavior can be reduced or eliminated by adding options to the invocation of kudzu (see the man page for the choices available). In particular, note the following from the man page: -s, --safe Do only 'safe' probes that won't disturb hardware. Currently, this disables the serial probe. So one could add the "--safe" option to the invocation line in /etc/rc.d/init.d/kudzu: /usr/sbin/kudzu -t 30 --safe or even (not recommended): /usr/sbin/kudzu -t 30 --quiet # do only configuration that doesn't require user input (better to just wait 30 seconds) One could also hand edit /etc/sysconfig/hwconf and add: driver: ignore to the appropriate sections (guesswork -- poorly documented). Better yet, complain to RedHat about the lack of documentation, and the need for a line oriented mode for kudzu, for use with adaptive hardware (possibly with a patch submission, for those who have the skills).

I personally never needed > it after the initial Red Hat installation. You may have a point. I hadn't thought about it from that angle. I guess it depends on how often the user changes their hardware, and how confident or experienced they are. Ultimately, though, unless one has full access the the GUI or other menu oriented configuration interface, learning to read documentation and edit text config files is the easiest way out (and often it is still the easiest way, even _with_ the GUI). But it's been too long since I was at that level for me to say for sure -- come to think of it, I learned at the text level, before the menu stuff even became available. Anyway, I can see that, for many users, turning kudzu off is a good option. They can always run it from the command line, if it is needed. LCR -- L. C.

Robinson @ ` Janina Sajka ` Dave Mielke ` Jude DaShiell 1 sibling, 1 reply; 18+ messages in thread From: Janina Sajka @ UTC (permalink / raw) To: blinux-list Not that anyone asked ... But I though I'd throw in my 2 cents regarding kudzu. I have turned it off on my portable system. I find it's just a nuisance when I need to boot because it comes up too often asking me to remove something that it will then ask me to add next time I have the system docked. I find it easier to simply run kudzu from the command line when I truly have new hardware that requires configuration. It's not hard to remember this. Frankly, I don't do this on my office systems, because it's not a problem there. I rarely boot them, and when I do, it's usually a matter of new hardware, so I appreciate kudzu at those times. But the other question in the current circumstance with John seems to be that the braille display should be registered somehow with linux as a recognized and supported device, so that it will not be probed and reset by kudzu. Am I wrong about this? ^ permalink raw reply [flat|nested] 18+ messages in thread

Am I wrong about this? Even if it were registered with Linux, kudzu wouldn't be able to know what it was without probing it. The problem is that the device (the braille display) is already up and running, so, when kudzu sends probing data to it, it gets out of sync with what BRLTTY is doing with it. -- Dave Mielke | 2213 Fox Crescent | I believe that the Bible is the Phone: 1-613-726-0014 | Ottawa, Ontario | Word of God.

Why it is any of these versions of Linux were ever sold that omitted the bsd learn utility package. When I started learning unix, I got a pointer from a friend to go and try that out. Admittedly it didn't cover such sysadmin things like permanently disabling the portmap server and what could happen to your system if you didn't get that done, but it was written at least the version I used before 1989 and viruses were not then as they are now. I got infested with linsniffer by the way. Not a pleasant experience. I'll try exportfs -ua to handle the portmap server since I really don't need it on. Maybe it will be needed for ethernet but I can't figure how. If anyone does a search for linsniffer, the info on it is on attrition.org.

I also checked to make sure I was in a text console mode. There is a message that says "init level 3", so that should be ok. Now when i boot the login: prompt comes up briefly and then disappears. However, the advance bars stil do not work consistently, the window left, dot 3, and window right, dot 6, do not work at all.

Did you try the latest (version 2.99 if I remember correctly)? If your problems persist you may check with Stephane Doyon (e-mail address in CC) who worked on the BrailleLite a lot recently.

John, you're sure that you aren't being brought up in Xwindows; I know you mentioned checking whether you are in a text console, but double check. What happens when you try to change consoles with alt-function key if you're on 1 then try f2 for instance). (on my keyboard with its current map that has to be the left alt). I could be totally wrong, but I think this maybe something in your system's interaction with brltty and not just a brltty problem. ^ permalink raw reply [flat|nested] 18+ messages in thread

Firstly, it'll happen if your system is set up to start the X gui (still a possibility, but not likely since you said you noticed an "init level 3" message). Secondly, it'll happen if something's displaying an error message after the login prompt has been written. If it's this latter case, then pressing enter again should get the login prompt back.

While John is new to linux, he is an experienced unix user so I don't know that he'd find editing a file, if he knows what he needs to change, frightening. As for me, as a total newbie to linux when I started, it was frightening the first time I had to edit something, but I had patient helpers like people on this list who told me exactly what to do (and reminded me not to do my linux editing in DOS) and I got over being frightened of it pretty quickly. I've learned when in doubt to make a backup of the file I'm going to edit, even if I think my editor is also going to do so, so that I can allways get back to status quo if something goes wrong. As for the need for kudzu once installation is over, that's something of which I have no knowledge so I won't even try to comment. ^ permalink raw reply [flat|nested] 18+ messages in thread
