Tiny Core Base > Corepure64

Browsers & Many Apps don't start after changing display resolution to 1920x1080

(1/2) > >>

chikunjiho920@gmail.com:
running TinyCorePure64 version 16.12.11 in
Oracle VirtualBox Version 7.1.10 r169112 (Qt6.5.3) in
Windows 11 Home 24H2 - 26100.4351 on
AMD Ryzen 5 5625U Acer Aspire Light and Thin Laptop with 48GB RAM ( 16GB + 32GB) & 512GB SSD NVMe M.2 2280 PCIe3.0

1). I first changed the Display Resolution to 1920x1080 How? Went to Prompt by pressing Ctrl + Alt + Backspace.
Thereafter, >$ tce-load -wi open-vm-tools-desktop
>$ startx
When in GUI Desktop mode in the Terminal
>$ xrandr -s 1920x1080
>$ startx

2). Installed FireFox
from the App center

3). When I tried to start it from the Wbar or the Menu or from the Terminal it won't start.

4). I installed vivaldi, brave, chromium, netsurf, midori, opera 62, iridium and whatever browsers you have and they won't start after installing.

5). However, when I installed XFE file manager it would start, VLC would start, libreOffice would start.

6). Geany would not start

7) Except for Opera-12 which is the only browser that starts. However, there are some certificates issues and most sites don't work.

So why are these programs not starting? How can I get them to start/work? Please help.

Even without changing the Display Resolution. When I try to install FireFox;

I am getting this error:
XPCOMGlueLoad error for file /tmp/tcloop/firefox/usr/local/firefox/libmozgtk.so:/usr/local/lib/libatk-1.0.so.0: undefined symbol: g_once_init_enter_pointer
Couldn't load XPCOM.

Are the extensions up to date (run 'tce-update')?

On TC16 x86_64 /usr/local/lib/libatk-1.0.so.0 has g_once_init_enter_pointer, so it seems you must be using an older version of the at-spi2-core extension, or perhaps there's some filesystem corruption:


--- Code: ---$ tce-load -i binutils
flex.tcz: OK
binutils.tcz: OK
$ nm -D /usr/local/lib/libatk-1.0.so.0 | grep g_once_init_enter_pointer
                 U g_once_init_enter_pointer
$ ls -l /usr/local/lib/libatk-1.0.so.0
lrwxrwxrwx    1 root     root            54 Jul  5 10:04 /usr/local/lib/libatk-1.0.so.0 -> /tmp/tcloop/at-spi2-core/usr/local/lib/libatk-1.0.so.0

--- End code ---

I'm not sure if this is related to the display resolution issue. I never use screen resolutions that high so I don't really know if there are extra quirks.

Hi chikunjiho920@gmail.com
/tmp/tcloop/firefox/usr/local/firefox/libmozgtk.so:/usr/local/lib/libatk-1.0.so.0 appears
to come from firefox-ESR.tcz.

I see you installed firefox_getLatest.tcz. After you run that you will have a firefox.tcz
extension available.

Using the Apps GUI, select Apps->Maintenance->Onboot Maintenance
Add  firefox.tcz  to  onboot.lst
Remove all other firefox extensions (firefox-ESR, firefox-nightly, etc.) from onboot.lst
Reboot the system
