[Solved] My Geany is slow on TC 11.1 + Xorg!

[elf]

Hi!
At first, I feel sorry that I'm a newbie to Linux and English is a foreign language to me.

Anyway I have a problem on using geany with Xorg-7.7 (on TinyCore 11.1). It's slow especially when I scroll up a text on it.

With Xvesa it's really smooth.
And I used to use Puppy Linux  5.7.0 (on the same PC) where geany (1.23.1) works really fine.

I tried Leafpad and beaver. They had the same problem. And GVim wasn't worse but still bad. L3afpad wasn't bad but not ideal again. The pre-installed 'editor' works perfect, but I need more powerfull undo-redo function at least...
Using jwm instead flwm made no change.

My laptop is DELL Inspiron 1210(Intel Atom Z530).
And here's my onboot.lst.

Code: [Select]

kmaps.tcz
xf86-video-intel.tcz
xf86-video-intel-i810.tcz
graphics-5.4.3-tinycore.tcz
Xorg-7.7.tcz
Xorg-7.7-3d.tcz
aterm.tcz
flwm.tcz
ttf-bitstream-vera.tcz
geany.tcz

I'm almost giving up finding a solution for the problem now. Because I feel Xvesa is acceptable to me for now.
But if someone happens to know about the problem(and the solution for it. Maybe I'm just missing some basic things? or some relevant information in this forum?), please give me a hint. Thanks!

Hi, elf!

I use TinyCore on the laptops with Atom Z-series too (mine are ASUS 1201HA with Z520) so I will be able to test some solutions if needed. Z-series is equipped with GMA500 video subsystem, which is not Intel video (!). It has absolutely no 3d features - at all.

1. Have You tried not loading Xorg-7.7-3d in onboot.lst? I expect it is absolutely unnecessary.
2. xf86-video-intel and xf86-video-intel-i810 includes different versions of the same librariess, so I think You need to choose one of these extensions, probably xf86-video-intel.
3. Try to move graphics-5.4.3-tinycore to the top of Your onboot.lst

One more qestion: have You tried TC10? There are some differences in how kernel treats GMA500 between TC10 and TC11 not in favor of the last.

Have a nice Core!

This one?
https://en.wikipedia.org/wiki/Dell_Inspiron_Mini_Series

That says the laptop uses Poulsbo graphics (PowerVR, which Intel just rebadged for those models). There is no good driver for that, -i810 and -intel only work for real Intel chips. You're going to use vesa or modesetting with Xorg, or Xvesa. Your list doesn't include xf86-video-vesa, so you're probably using modesetting right now.

[jazzbiker]

xf86-video-vesa is among the dependencies of Xorg-7.7.

I've compared geany under Xorg and Xfbdev. Under Xorg scrolling up is very slow, while scrolling down is fast enough, even can say fast. Under Xfbdev both directions have the same speed of scrolling, something between scrolling speeds under Xorg. Probably geany is trying use for scrolling up some functions, which are absent. In both cases were loaded graphics-5.4.3-tinycore as the very first extension, Xorg or Xfbdev, then other desktop stuff.
I've tried firefox and seamonkey-noSSE2, they shows smooth scrolling. I felt no differences, depending on the X server.

Hello, jazzbiker & curaga! Thank you for your replies!

First of all, I didn't notice about GMA500's disadvantages. Interesting! Fortunately I don't need 3D graphics and expect so much 2D graphics power on this machine.

   to jazzbiker:
Yeah, I had tried all of your suggestions about "onboot.lst" pattern, but things were same...
And now I tried TC10(and TC6 which seems have rather near release date with PuppyLinux 5.7.0.), but same old same old...
Xfbdev's response to mouse wheel scroll is nice! But to keybord is terrible, isn't it?
I'm guessing that this phenomenon has something to do with GTK's editable text area(or something like that).
And I'm wondering what's the difference between TinyCore and the (old) Puppy...
Anyway thanks for your suggestions and tries! They were really informative to me!
(And sorry, maybe I'm misunderstanding your last post because of my English skill... I couldn't catch "among the dependencies" and "In both cases were loaded..." well.)

   to curaga:

Yes, that's what I have!

Poulsbo! Ahh, so my Xorg.0.log says like...

Code: [Select]

I had wondered "what's psb?" Eureka!

About modesetting, probably you are right. I'm not sure about how to read the log, though...

[jazzbiker]

Hi, elf!

~/.config/geany/geany.conf has no parameter responsible for turning scrolling off. Maybe it can be done while compiling. You can try to build Your own geany without scrolling, if it is possible.

English is not my native language, too, that's why my posts may not be understandable well, sorry.

[jazzbiker]

Unfortunately https://www.x.org/archive/individual/driver/ directory have no signs of Poulsbo driver Is it possible that it is hiding in some xf86-video-intel*.tar.gz?

Seems, that we need not fbdev, but some fbdevhw driver. Right?

I'm trying to compile xf86-video-fbdev, loaded from  https://www.x.org/archive/individual/driver/ but configure exits upon error:

Code: [Select]

configure: error: Package requirements (xorg-server >= 1.0.99.901 xproto fontsproto  randrproto renderproto videoproto) were not met:

I've loaded xorg-server-dev, Xorg-7.7-dev. Is it possible to satisfy this dri dependency?

Thanks in advance!

Xorg-7.7-3d-dev was needed.

Hi, jazzbiker!
I can't appriciate you more! and I'm feeling terribly sorry...

About xf86-video-fbdev.tcz, TinyCore 6 repo has it, but the module version wasn't compatible with TinyCore 11.
So I checked Xorg.0.log of TC6.

In my case, loading fbdevhw failed after all. Hmm...

And here's Puppy's Xorg.0.log. This might be irrelevant information. It seems be using rather different libs from TC(and your Lubuntu).

Now that I know you have same experience on your ASUS machine, I have some feeling like
"So be it! Anyway this happens not only to me. I might be able to go with this awkward scroll movement!"
So, unless you are willing to go further about this problem for yourself, please don't use your resources any more!
Of course, I will keep searching and studying about this glitch my own pace. It's fun! I believe you have same feeling!
Thank you!

The psb driver was a binary blob that only worked on a specific old version of Ubuntu.

I've captured lsmod-s on above mentioned Lubuntu 14.04 and TinyCore 10.1 (graphics-KERNEL loaded) and cleaned them manually from everything not dealing with graphics. Here's what I've got:

TC engages agpgart, in Lubuntu gma500_gfx is much bigger. Others seem to be alike. Is the trick inside gma500_gfx?

Maybe this boot code would help:
