I searched the forum with a couple variations on my question first and "no results found" . . . so I'm posting it as a new topic. About a month ago, I've posted this question on the Linux MInt forum, asking for some insight into not just why this problem is happening, but some ways to fix the problem, and so far . . . no answers that could lead to a solution to it have been offered there. A couple weeks ago I posted on the Ubuntu Apple user forum, same thing; so now I'm trying here, where in the past I've gotten not only replies . . . but actual help to fix the problem. This problem might be more rare, but I did see quite a few others posting about erratic cursor movement in Google search . . . but again, no answers found there. According to the sources list Linux Mint is essentially Ubuntu hotted up, so the problem might be there? Or, in something that LM has added? I'm pasting a couple of the first posts on the LM forum, I think I moved it from "newbie" to "software issues" between the two pasted here . . . .
Anyway--to make it short, typing, like I am now, usually in an online forum or Gmail online, in a MBPro, and running LM13 MATE 64 bit--suddenly cursor will jump . . . back in the text previously typed . . . and many times it will highlight all the text in between, and then erase it. If I catch it, I can ctrl-z it back, but if I miss it and hit another key . . . the text is gone. I've lost 20 minutes of work that way; like to figure it out and fix it. Problem happens in Cinnamon, MATE, XFCE, GNOME, and Ubuntu DEs . . . and I thought it was a FF issue, but problem also happens in Midori as well . . . don't have any other browser loaded. Any insights into the issue would be appreciated. The problem has happened with some regularity, now probably at least 15 times--I've updated and upgraded the system a couple times with no changes to the problem.
LM forum posts [software isues]:
Moving this post over to a new topic, I searched the forum here, as well as google, and saw reference to mouse/cursor moving erratically, or losing control of mouse, and there was a bug report from Sept '12, that I couldn't find buried in the list of bug reports with a similar issue as mine, but no solutions found. The problem is that the mouse/cursor will suddenly jump back in an email, usually in a browser, and the typing will just start there; and more annoyingly, sometimes the text between where it was and where it ends up, will be erased. It might be in this post, after almost getting to the end, suddenly it will all be erased. I couldn't find any insights into this problem, so I'm posting here. Actually there was a post from someone in LM14 with the jumping cursor problem, the answer given by someone was to update the xserver-xorg-core file . . . I checked mine in synaptic and it's as new as it can be for LM13. Perhaps someone can offer some insights? The code above is showing the errors that came when I tried to install Chromium . . . in both Synaptic and Terminal.
[Previous post moved to here [newbie questions]]:
Yes, problem happened again yesterday while typing in a forum post, so in FF . . . no spare fingers touching the touchpad, just suddenly the cursor moved back in the text, erasing almost everything that was written . . . . Fortunately I was awake and noticed what happened and could ctrl-z it back. But, this really isn't acceptable behavior from an OS, is this passive-aggression from somebody where a glitch is placed so that we keep it real?
Anyway, in the interest of trying to figure out if it's an FF problem I tried synaptic to install another browser, I tried chromium, but got the above error(s) . . . seamonkey did not show up . . . . Is FF the only browser that works with LM13? I did see a post somewhere about how the cursor will up and move 90 degrees, but couldn't find it again and couldn't remember if it had to do with apple computers or any computer. So, haven't been able to confine the problem to being cursor related, touchpad, or browser . . . and then it seems like FF is the only big box browser we have?? I like to have several browsers to choose from depending on my mood . . . .
P.S. Later that same day: Managed to install Midori thru synaptic and fiddling around getting it set up . . . looks like it was a 3MB download, seems fast enough, doesn't seem to have auto-fill for log in windows. I'll be testing it to see if the same erratic cursor and lost data problem happens in Midori, or if it's just confined to FF. [Comment]: The problem happened in Midori as well yesterday, so it's not just FF that is causing the problem.
There are more posts in the thread, mostly from me.
