Improving responsiveness of rxvt
I recently installed Slackware in dual boot beside Arch.
I am sure there might be dozen of things to consider or look at but I am not clear as to how to proceed with the folowing. I installed rxvt-unicode from Slackbuild.org and it seems not to respond as fast as it does when used in Arch. There is that fraction of a second where it seems to hang when typing. Out of curiosity, I modified the slackbuild script to reflect the PKGBUILD in Arch, reinstalled rxvt and yet no improvement. So is there a specific area I should look at? Thanks all. |
Hi and welcome to the Club :cool:
IIRC a possible culprit *could* be the nouveau version included in Slackware 13.37, as I observed that with it but not with a more recent one nor with the blob that I am right now using. But I usually run xterm, not rxvt-unicode. Did you try with an xterm and does that make any difference? I will switch to nouveau later today and will tell you if I still observe this behavior. Meanwhile, what are your GPU kernel driver + X module used for video? If it's Intel or ATI my assumption can be safely moved to /dev/null ;) "lspci -k| grep -A3 VGA" is usually enough to answer that. OTOH, would it be right you just would have to wait a few days till Slackware 14 be released (if, indeed, you are not already running Slackware-current). |
Hi,
do you use antialiasing? i have had the same "problem" with rxvt-unicode, i disabled antialiasing and now it's ok. regards fl0 |
@Didier. Thanks for the welcome. :)
My graphic card is nvidia... Quote:
I am running Slackware 13.37 at the moment. I briefly tried xterm. Hard to tell. I will see if I can customize it a bit i.e. no border, black background and see how it goes. @fl0. No I don't use antialiasing In fact, this is my configuration Quote:

I can't try now (it's late in Paris) but tomorrow I will switch ton nouveau in both Slackware 13.37 and Slackware current. If I see a difference I will try a more recent version of nouveau in Slackware 13.37 and tell you the results, both with xterm and urxvt.

Nothing really obvious here using nouveau. I have an awk script started from an xterm and spitting one line of text every 4 seconds. Sometime the first horizontal half of a line line is displayed first, then the second half. But the script is very CPU hungry so that may not be significant.
You could check that the nouveau driver *could* be involved with "cp /etc/X11/xorg.conf.vesa /etc/X11/xorg.conf" and restart X to see if there is any change using the vesa driver instead of nouveau. |

I am on Slackware 14-RC5 now.
I confirm that xterm looks more responsive. I don't know for urxvt as I didn't install it yet. |

On my older PC I've also encountered this issue with urxvt. I believe the problem was solved by installing the nvidia driver.

Was a duplicate post.

Well, I try rebooting with an xorg.conf but the screen resolution kind of suck. I set up terminator to my liking and will go with that. It has been a learning experience :).
